10.8 Questions and Answers
Q: To build a heap from a set of data
using the interface presented in this chapter, we call heap_insert once for each element in
the set. Since heap_insert runs
in O (lg n)
time, building a heap of n
nodes requires O (n lg n) time. What is an alternative to
this approach that runs in O
(n) time?
A: An alternative to calling heap_insert repeatedly is to start
with an array of nodes that we heapify by pushing data
downward just as is done in heap_insert. In this approach, we
first heapify the tree whose root is at position n/2 - 1, then heapify the tree whose
root is at position n/2 - 2,
and continue this process until we heapify the tree rooted at
position 0. This approach relies on the observation that the
nodes at n/2 to n - 1 (in a zero-indexed array) are
one-node heaps themselves because they are the leaf nodes.
Building a heap in this way is efficient because although
there are n/2 - 1 operations
that run in O (lg n) time, a tighter analysis reveals
that even in the worst case only half the heapifications
require comparing data at more than one level. This results in
an O (n) running time overall. On the other
hand, when calling heap_insert
repeatedly, half the heapifications could require traversing
all lg n levels in the worst
case. Thus, building a heap in this way runs in O (n
lg n) time.
Q: Why are
heap_ parent, heap_left,
and heap_right defined in heap.c, whereas the other heap macro,
heap_size, is defined in heap.h?
A: The macros
heap_ parent, heap_left, and heap_right quickly determine the
position of a node's parent, left child, and right child in a
tree represented in an array. The reason these macros are not
defined in heap.h is that they are not a part of the
public heap interface. That is, a developer using a heap
should not be permitted to traverse a heap's nodes
indiscriminately. Instead, access to the heap is restricted to
those operations defined by the interface published in
heap.h.
Q: Recall that
left-balanced binary trees are particularly well-suited to
arrays. Why is this not true of all binary trees?
A: Left-balanced binary trees are
particularly well-suited to arrays because no nodes go unused
between positions and n - 1,
where n is the number of nodes
in the tree. Array representations of binary trees that are
not left-balanced, on the other hand, contain gaps of unused
nodes. For example, suppose a binary tree of 10 levels is
completely full through 9 levels, but in the tenth level only
1 node resides at the far right. In contiguous storage, the
node at the far right of the tenth level resides at position
210 - 2 = 1022 (in a zero-indexed array). The node
at the far right of the ninth level resides at position
29 - 2 = 510. This results in (1022 - 510) - 1= 511
empty positions out of the total 1023 positions required to
represent the tree. Thus, only 50% of the array is being
used.
Q: Suppose we are using a priority
queue to prioritize the order in which tasks are scheduled by
an application. If the system continually processes a large
number of high-priority tasks, what problems might the system
exhibit? How can we correct this?
A: When
high-priority elements are continually being inserted into a
priority queue, lower-priority elements may never rise to the
top. In a task scheduler, for example, the lower-priority
tasks are said to be experiencing starvation.
To manage this, typically a system employs some mechanism to
increase a task's priority gradually as its time in the queue
grows. Thus, even in a busy system flooded by high-priority
tasks, a low-priority task eventually will obtain a high
enough priority to rise to the top. Operating systems
frequently use an approach like this to ensure that
lower-priority processes are not completely starved of CPU
time.

APTOPIX California Party Shooting
by Associated Press1 / 4Police and emergency personnel are on the scene of a shooting at a backyard party, Sunday, Nov. 17, 2019, in southeast Fresno, Calif. Multiple people were shot and at least four of them were killed Sunday at a party in Fresno when suspects sneaked into the backyard and fired into the crowd, police said. (Larry Valenzuela//The Fresno Bee via AP)
FRESNO, Calif. (AP) — The Latest on a deadly shooting at a backyard party in central California (all times local):
10 a.m.
People who live on a central California street where four people were killed during a party say it had been peaceful for years but that shootings have been happening in the neighborhood in recent weeks.
Calvin Gatison said Monday that the Fresno street of single-family homes with manicured front yards is quiet during the week, while grandfathers can be seen playing with grandchildren on their front yards on weekends. He says other neighbors host gatherings in their backyards.
A backyard party is where a shooting Sunday killed four and wounded six others. Authorities are looking for suspects and don’t know a motive.
Gatison says he has heard shots ring out at least twice in the neighborhood in recent weeks. But he says his street is always quiet because even during parties, he never hears loud music.
He says that “for something like this to happen in a quiet neighborhood, it scares you.”
___
6:45 a.m.
As police search for suspects and a motive in the killing of four people at a backyard party in Fresno, California, neighbors say they are scared because there have been other shootings in the same neighborhood recently.
Choua Vang tells the Fresno Bee in a story published Monday that his neighbor’s house was shot at last week and that he feels unsafe being outside after dark.
Ten people were shot in Sunday’s shooting. Authorities have said “unknown suspects” sneaked into the backyard filled with people at the party and fired into the crowd.
Vang says he is worried about his family members who work overnight shifts and that his family is thinking of moving out of the Fresno neighborhood.
Fresno Police spokesman Lt. Mark Hudson did not immediately return email and phone messages Monday seeking comment.
___
This item corrects the date to Monday, not Friday.
___
10:10 p.m. Sunday
Police in central California say 10 people were shot at a backyard party, and four them died.
Fresno police say the shooting took place about 6 p.m. Sunday on the city’s southeastern side.
Fresno Police Deputy Chief Michael Reid tells the Fresno Bee and the KSEE/KGPE TV stations that 10 people were shot, and three people were found dead in the backyard. A fourth victim died at the hospital.
Police say six others are expected to survive and are recovering at the hospital.
It was at least the second fatal gun attack Sunday in southeast Fresno.
A man in his 20s was shot to death early Sunday at a home in another part of the city. Police have not said whether the incidents could be connected.

Now I remember why I do this job…
Today I had one of those days you get as a programmer, when everything coalesces in a perfect way to shine a happy light on the universe. I had a list of bugs and a single feature I wanted to add to my Flex program. The single feature (dynamic filtering based on values in a set of arrays) took me a long time, and I wrestled with it mightily for several hours. I wanted desperately to make a filter which was extensible, which was easy to add new fields to, and passing variables around in Flex is not something I’ve become comfortable with.
So there I was, pounding my head against the thing, frustrated and feeling incompetent, until 4PM when a light shined down upon me from the sky, the scales fell from my eyes, whatever cliche you want to use… and the feature was complete. And when the dust cleared, I realized that 3 of the bugs on my ‘to-do’ list had gotten fixed in the process of creating this feature.
It’s an awesome day when you feel “done” with what you’re working on. I wasn’t even tempted to start on something else… I just basked in the glow of having gotten it done.
For anyone wandering here from flex land who wants to see the code, here it is:
private var filterObj:Object = {this:filterThis,that:filterThat}; // These arrays are populated elsewhere with a list of strings to filter on private var textObj:Object = {this:"",that:""}; private function filterAll():void { var filtered:Boolean = false; var filterType:String; for (filterType in filterObj) { if (filterObj[filterType].length > 0) filtered = true; } if (filtered) { dataSet.filterFunction = filterGeneralSet; dataSet.refresh(); } else { dataSet.filterFunction = null; dataSet.refresh(); } private function filterGeneralSet(item:XML):Boolean { var filterType:String; var element:String; var myArray:Array; // This is an 'and' filter where everything has to match for the element to return true for (filterType in filterObj) { if (filterObj[filterType].length > 0) { myArray = filterObj[filterType]; for each (element in filterObj[filterType]) { var itemFilter:String = item.child(filterType)[0]; if (itemFilter != element) { return false; } } } } return true; }

Bailing on New York
Not long after announcing his departure from New York as his permanent residence outside of the White House, US President Donald Trump decided to dig into the New York Governor Andrew Cuomo and New York City Mayor Bill de Blasio over the state’s bail reform and the Big Apple’s current condition.
At the top of the year, the state of New York’s bail reform law will go into effect, eliminating money bail and allowing those accused of an array of misdemeanors and non-violent felonies to walk free until their court date. However, according to Fox News, some 900 inmates from the state will be released under similar guidelines as soon as next month.
According to Vera Institute of Justice, the pretrial jail population in New York will drop by at least 40% following the law’s implementation.
De Blasio rejected Trump’s assertion that the city of New York was “rapidly” declining under his watch and argued that the community is actually safer without Trump around.
Cuomo’s spokesperson, on the other hand, said the governor had “no knowledge” of the early releases reported by Trump and various news outlets, according to the New York Post.

The ".org" files still disappear extra-headers, `#+EXTRA-YAML-HEADERS: theme: blah\nplugin:
I don't understand this sentence.
Sorry, I'd mistake the sentence. It's lack a word of "not".
I want to do is :
when I create a new draft after org2jekyll-create-drafts, it's appear such:
#+STARTUP: showall #+STARTUP: hidestars #+OPTIONS: H:2 num:nil tags:nil toc:nil timestamps:t #+LAYOUT: post #+AUTHOR: yefeiyu #+DATE: 2016-04-19 二 20:56 #+TITLE: c #+DESCRIPTION: #+TAGS: #+CATEGORIES: #+EXTRA-YAML-HEADERS: theme: blah\nplugin: lightense\nscheme-text: ""\nscheme-link: ""\nscheme-hover: ""\nscheme-code: ""\nscheme-bg: ""\nscheme-hero-text: ""\nscheme-hero-link: ""\nscheme-hero-bg: ""\n
Now, I can do this by `yasnippet`. I created a new snippet in the `~/.emacs.d/snippets/org-mode` fold:
# -*- mode: snippet -*- # name: oc # key: oc # -- #+EXTRA-YAML-HEADERS: theme: blah\nplugin: lightense\nscheme-text: ""\nscheme-link: ""\nscheme-hover: ""\nscheme-code: ""\nscheme-bg: ""\nscheme-hero-text: ""\nscheme-hero-link: ""\nscheme-hero-bg: ""\n $0
So I can add the `#+EXTRA-YAML-HEADERS…etc` easy. the only regret thing is it need my input `oc TAB` every time, in each article. (After this step, I can definned colors)
Thank you again. It's very comfortable to use org2jekyll, and I'll introducing it to others.

The first step in a phenoptrReports
data analysis is data consolidation.
The consolidation step combines the output from multiple inForm projects into a single consolidated data file and creates columns for each individual phenotype. The inputs to this step are merged cell seg data files from multiple inForm projects. The output is a consolidated data file and a summary report for each file.
NOTE: The consolidation step will fail if the Slide IDs and Cell IDs in the merge files do not exactly agree. This can happen, for example, if
Run the consolidation step even if your data comes from a single inForm project. This creates a data file in the format that the analysis step uses.
The primary source data for phenoptrReports
is one or more merged cell seg data files created in the inForm Review/Merge tab. You may use multiple merge files from multiple inForm projects with different phenotypes. The Slide ID and Cell ID fields in multiple merge files must agree exactly.
Thus will open the consolidation app.
Click the “Browse Input” button in the “Select source data files” section of the GUI. Use the file selection dialog to select your inForm merge data files. If the files are in multiple directories, click the Browse button multiple times to select them.
Select “Keep only phenoptrReports fields” to reduce the size of the consolidated data file by omitting rarely used fields such as Min and Max expression and cell Compactness.
Click the “Browse Output” button in the “Select output directory” section of the GUI. Use the directory selection dialog to create a new directory to contain the output files.
Click the “Process Files” button to start processing of the selected files.
A small progress meter will open to show progress. Any errors will be shown in the RStudio Console pane.
When processing completes, the output directory will contain several files:

Pathvisio has recently added the feature to create MIM diagrams. We encourage users to provide us their comments, questions, and feedback.
An introduction to the MIM notation is provided in the 2006 publication: Molecular Interaction Maps of Bioregulatory Networks: A General Rubric for Systems Biology. There are currently several efforts to provide tools for the creation of MIM diagrams. One current tool, Pathvisio, provides functionality for creating and exporting MIM diagrams into several different formats. A manual on its usage is provided here.
Click here to download Pathvisio.This tool is a general pathway drawing tool that includes many MIM specific features. If you wish to create MIM specific diagrams, you will have to be selective in your choice of images. In the creation of interactions between species users can specify MIM interaction symbols as the start or end line types, these all begin with 'mim-'. This feature is located in the properties tab on the right-hand side of the editor.


Perry Mason TV director Arthur Marks dies aged 92
He also worked on The Dukes Of Hazzard and produced films targeted at black audiences.
Producer and director Arthur Marks, who helmed many episodes of the Perry Mason TV series and produced several hit blaxploitation films, died aged 92.
Marks died on November 13 at his home in Woodland Hills, California, his son Paul said.
“My brother and I learned everything about the film industry from my father,” said Paul Marks, who is a TV producer.
“He was a pillar of the industry.
“He taught us the morals of the industry and how to treat people.”
Arthur Marks’ grandparents and parents worked in the film business, and he grew up in it.
Marks was the director and producer of 80 episodes of Perry Mason.
He also directed episodes of the TV shows I Spy, Mannix and The Dukes Of Hazzard.
He made several films aimed at black audiences in the 1970s.
They include Detroit 9000, which was re-released in cinemas in 1998 by Quentin Tarantino, and two films starring actress Pam Grier: Friday Foster and Bucktown.
“I believe when you put in the mix; a good script, a terrific cast, an experienced and perceptive director and a professional production what is the result?
“A film that audiences will enjoy and play eight weeks in a downtown theatre in Chicago, Detroit or Kansas City,” Marks said.
“My intention was never to sell my films as a ‘black’ film, rather a film that will damn well entertain for 120 minutes…with excitement, passion and a heart moving story.”
In addition to his son Paul, Marks is survived by another son, Beau; two daughters, Kathleen and Elizabeth; six grandchildren; and five great grandchildren.

Counting events is a very useful programming technique for the testing/debugging/monitoring applications. It is widely used in CCore. The class Counters is designed to simplify this task.
template <EnumType Enum,Enum Lim,class CountType=unsigned>
class Counters : public PrintOptAdapter<Enum>
{
CountType counter[Lim];
public:
Counters();
void reset();
void count(Enum e) { counter[e]++; }
void count(Enum e,CountType cnt) { counter[e]+=cnt; }
CountType operator [] (Enum e) const { return counter[e]; }
void diff(Counters &next);
void operator += (const Counters &obj);
void operator -= (const Counters &base);
// print object
void print(PrinterType &out) const;
void print(PrinterType &out,const AnyType &opt) const;
};
Counters is a set of counters, indexed by members of some enum:
enum Enum { E1, E2, E3, Lim }; using EnumCounters = Counters<Enum,Lim> ;
The default constructor and the method reset() set all counters to zero.
The method count() increments or increments by some value the counter with the given index.
The overloaded operator [] reads the specific counter.
The overloaded operator += adds counters from another counter set.
The overloaded operator -= subtracts counters from another counter set.
You can use the method diff() to differentiate a sequence of counters:
Counters<Enum,Lim> cur; Counters<Enum,Lim> next; cur.diff(next); // // temp = cur ; // cur = next ; // next = next - temp ; //
Finally, you can print the counters, to give names to indexes define GetTextDesc(Enum). You may specify print options per enum. Only non-null counters are printed.
E1 = 5 E2 = 1 E3 = 15

If I have (a b c : Type) (f : a → b) (g : a → c)
, do we have a name or notation for the function mapping x
to (f x, g x)
?
We probably don't yet, but Haskell has one, if anyone wants to copy that
> :t (&&&) (&&&) :: Arrow a => a b c -> a b c' -> a b (c, c') > :t snd &&& fst snd &&& fst :: (a, c) -> (c, a)
where Arrow
is an abstraction of functions https://wiki.haskell.org/Arrow_tutorial
For this particular operator, applicative
is sufficient: x &&& y = prod.mk <$> x <*> y
(that is to say, we only need applicative (a b)
)
You're trying to scare me with your notations
It works pretty well
What works well? Scaring you or using the notation?
scaring me
Oh, good, so my work here is done
As far as I know, the definition is not in mathlib so you make it as simple as you need and leave it to others to generalize so that it looks more like Haskell (the generalization has a few stumbling blocks I think)
Ok, I may do that. But first I'll sleep. Thanks!
:+1:
Good night!
here’s some discussion on the Arrow class: https://www.eyrie.org/~zednenem/2017/07/twist
PureScript has opted not to create an Arrow class (see link 3 above); instead it just defined (&&&)
using Strong
and Category

I think in Haskell as well, people think Arrow might not have been the right abstraction

Is there actually any implementation anywhere apart from Function

haha, we can go one step away from Function with Star :wink: https://github.com/purescript/purescript-profunctor/blob/v4.0.0/src/Data/Profunctor/Star.purs#L70 (actually that package has a variety of profunctors, a number of which implement Strong)

k i just started a little dungeon so tell me what you think.
K so this is like the path leading to the entrance.
Here is the entrance. i guess you gas in to enter.
Here is the dungeon's begining. pretty much just a long boring hallway so i wont take screens of it all
Then theres a room with a Mana pool this is primarily where the monsters will be. the room goes upward for a little while so ill skip those screens also
The end is some gates. not sure how you will get over then but ill figure something out
(on the other side are harder monsters, the gate is pretty much just to protect the noob's from getting pwned)
And heres the final area after the gate.
Atm it looks kinda plain. Any suggestions on what i should add?

Hello I am Naim AlOmari, I was born in Abudahbi (1996) I lived there my first 20 years, then I moved to
Jordan to study civil engineering at AlYarmouk University (2013-2018), Actually it was a very hard
decisions.
I worked as a civil engineer in ALMANASEER READY MIX which is located in amman, then I moved to AlJUBAIL
Contacting Company as a site civil engineer and I was a victim of this epidemic ( corona virus or covid 19
).
I knew that web developing is the most opening field, so I decide to learn more about it and try to do my
best in this field, so I can go ahead with my future.
my aim of joining this course is to try to mix between the civil engineering and the software developing.

I have been having problems using the correct ( { ) or ( , ) or ( ; ) after each code, there were several times running the for function that I had incorrectly used ( , ) rather than ( ; )
It was confusing me why it didnt work and I went through the code line by line, repeating to myself (similar to the rubber ducky approach).
It was pretty frustrating. Until I realised that the console message sometimes actually tells me what is wrong!
I learn to read error messages on the console, and also sometimes looking out for simple errors and not always assuming that it was something major.
I am not sure how elegant this is. The Scooby challenge stumped me, there were objects in arrays. I didnt even know how to start so I looked at the answer for a hint, however while it was great to see that the answer worked, I didnt understand how it worked.
So I used the answer as a prompt to help me breakdown the task. I tried to visualise it by actually arranging out the objects and array. I also console log out each code when I had written it to see what is happening. Then I comment it out so that I dont lose it. And kept console logging each line.
While it was time consuming (rather than elegant), using the tools that were mentioned and having it worked felt really good! I realised that for me to really learn, I really needed lots of step by step explanations. I am hopeful in time that things will be easier to grasp so that I can write cleaner code but for now, it is better with lots of explanations so that I can always refer back to it and understand.
Pseudocode seemed to work best for me to understand a task and helped to breakdown daunting tasks. For every task, there needs to be a plan and pseudocode outlines the plan of attack.
It always helps to try something new but also to be wary that one can fall down a rabbit hole trying something, then trying to fix something only to discover that what they are asking for was completely different!
Rubber ducky method - I find myself talking to myself alot lately and it really works!
There are a few error messages that were easy to understand however some were not. I am sure in time we will be able to understand more of the messages as we become exposed to it.
Console.logging was very helpful for me to make sure the code is doing what I intended for the code to do or on the contrary what was the code doing.
Googling was a great source (like a prompt to give you a headstart) to write the code. The best thing is that there are multiple sources out there, if one explanation confuses you (i.e for me the too wordy ones) then there are always other sources.
Asking your peers for help - I havent had the chance to do this much, I am also abit behind so was great that there are questions already asked on the slack channel that helps the process.
Asking coaches for help - I haven’t done much of this but had sought help at the start. I am also quite fortunate that my partner is a software developer, so without having to wait to ask the questions of my coaches I was able to get it through him quickly.
Improving your process with reflection - Once the problem was solved, I found it helpful to run over my pseudocode again to rewrite and explain the issue and task better.

The `AsyncFunction` Constructor is the %AsyncFunction% intrinsic object and is a subclass of `Function`. When `AsyncFunction` is called as a function rather than as a constructor, it creates and initializes a new AsyncFunction object. Thus the function call `AsyncFunction(…)` is equivalent to the object creation expression `new AsyncFunction(…)` with the same arguments.
The `AsyncFunction` constructor is designed to be subclassable. It may be used as the value of an extends clause of a class definition. Subclass constructors that intend to inherit the specified AsyncFunction behaviour must include a super call to the AsyncFunction constructor to create and initialize a subclass instances with the internal slots necessary for built-in async function behaviour.
The last argument specifies the body (executable code) of an async function. Any preceding arguments specify formal parameters.
When the `AsyncFunction` function is called with some arguments _p1_, _p2_, ..., _pn_, _body_ (where _n_ might be 0, that is, there are no _p_ arguments, and where _body_ might also not be provided), the following steps are taken:
The AsyncFunction constructor is a standard built-in function object that inherits from the `Function` constructor. The value of the [[Prototype]] internal slot of the AsyncFunction constructor is the intrinsic object %Function%.
The value of the [[Extensible]] internal slot of the AsyncFunction constructor is *true*.
The value of the *name* property of the AsyncFunction is "AsyncFunction".
The AsyncFunction constructor has the following properties:
This is a data property with a value of 1. This property has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*, [[Configurable]]: *true* }.
The intitial value of `AsyncFunction.prototype` is the intrinsic object %AsyncFunctionPrototype%.
This property has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*, [[Configurable]]: *false* }.
The AsyncFunction prototype object is an ordinary object. In addition to being the value of the prototpe property of the %AsyncFunction% instrinsic, it is the %AsyncFunctionPrototype% intrinsic.
The value of the [[Prototype]] internal slot of the AsyncFunction prototype object is the %FunctionPrototype% intrinsic object. The initial value of the [[Extensible]] internal slot of the AsyncFunction prototype object is *true*.
The AsyncFunction prototype object does not have a prototype property.
The initial value of `AsyncFunction.prototype.constructor` is the intrinsic object %AsyncFunction%
This property has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*, [[Configurable]]: *true* }.
The initial value of the @@toStringTag property is the string value "AsyncFunction".
This property has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*, [[Configurable]]: *true* }.
Every AsyncFunction instance is an ECMAScript function object and has the internal slots listed in Table 27. The value of the [[FunctionKind]] internal slot for all such instances is `"normal"`. AsyncFunction instances are not constructors and do not have a [[Construct]] internal slot. AsyncFunction instances do not have a prototype property as they are not constructable.
Each AsyncFunction instance has the following own properties:
The value of the *length* property is an integer that indicates the typical number of arguments expected by the AsyncFunction. However, the language permits the function to be invoked with some other number of arguments. The behaviour of an AsyncFunction when invoked on a number of arguments other than the number specified by its length property depends on the function.
This property has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*, [[Configurable]]: *true* }.
The specification for the `name` property of Function instances given in <IP_ADDRESS> also applies to AsyncFunction instances.


‘I Watched P0rn In My Hotel Room Back In Nigeria’- Cardi B
by Ghbase New WriterUS rapper Cardi B is still the hottest commodity on our part of the social media landscape after the drama which preceded her energetic performance last night at the Accra Sports Stadium.
The Bodak Yellow hit maker admitted she watched porn movies during her stay in Nigeria in an interview on Nigeria-based Cool FM.
Cardi B, who was interviewed by media personalities, N6 and Taymi, described Nigerians as “great entertainers”.
She proceeded to talk about Davido, Burna Boy and her love for the country.
As we all know, some Ghanaian celebrities are ‘bleeding’ after Cardi B refused (well it turned out that it wasn’t deliberate as she had no idea a formality like that has been arranged) to meet them in a Meet and Greet session at the Kempinski Hotel in Accra.

Abstract Base Class Radio.
This is an abstract base class which supports all basic functions radios have. In pariticular, it supports the TEA5767 and RDA58XX Series. RDA58XX Chips also have a compatibility mode in which they support basic functionality of the TEA5767 (addres: 0x60). Thus the TEA5767 Methods are alco compatible with the RDA58XX Series chips.

Constuctor.
This constructor has only one parameter; the I2C bus. The address is optional because both the TEA5767 and RDA58XX Series (through a compatibility mode) support communication via 0x60. Though the address can also be set manually or to 0x10 for the RDA5807's full feature package. One can also pass the bandlimit:

China says RCEP trade deal could provide opportunities for India's exports
BEIJING, Nov 6 ― China today sought to assure India over the Regional Comprehensive Economic Partnership (RCEP), saying the trade deal could provide many opportunities for India's exports.
China joined 14 countries this week in agreeing terms for RCEP, which could become the world's biggest free trade deal if officially signed next year as planned.
But India pulled out at the last minute amid worries that the deal would unleash cheaper imports from countries like China that render its own industries uncompetitive and hurt its farmers, businesses, workers and consumers.
Vice commerce minister Wang Shouwen, speaking at a news briefing in Beijing, said he understood those concerns, but the deal could benefit Indian exporters and help create more local jobs.
“We understand that some industries in India will have some concerns, but RCEP will also bring huge export opportunities to the Indian industry,” he said, adding that the deal includes a protection mechanism that can be used to put the tariffs back on if India does find the deal damaging to its domestic industries.
Wang applauded the trade pact as providing a “very significant boost” to investor confidence in the global economy against the rise of unilateralism and protectionism that has depressed trade growth across the world.
He said the deal would also greatly benefit Chinese firms, workers and consumers, as it would remove tariffs and non-tariff barriers, and bring down costs. ― Reuters

Identifiers are used to give names to several classes of language objects and refer to these objects by name later:
These eleven name spaces are distinguished both by the context and by the capitalization of the identifier: whether the first letter of the identifier is in lowercase (written lowercase-ident below) or in uppercase (written capitalized-ident). Underscore is considered a lowercase letter for this purpose.
|
As shown above, prefix and infix symbols as well as some keywords can be used as value names, provided they are written between parentheses. The capitalization rules are summarized in the table below.
| Name space | Case of first letter |
| Values | lowercase |
| Constructors | uppercase |
| Labels | lowercase |
| Variant tags | uppercase |
| Exceptions | uppercase |
| Type constructors | lowercase |
| Record fields | lowercase |
| Classes | lowercase |
| Instance variables | lowercase |
| Methods | lowercase |
| Modules | uppercase |
| Module types | any |
Note on variant tags: the current implementation accepts lowercase variant tags in addition to uppercase variant tags, but we suggest you avoid lowercase variant tags for portability and compatibility with future OCaml versions.
A named object can be referred to either by its name (following the usual static scoping rules for names) or by an access path prefix . name, where prefix designates a module and name is the name of an object defined in that module. The first component of the path, prefix, is either a simple module name or an access path name1 . name2 …, in case the defining module is itself nested inside other modules. For referring to type constructors or module types, the prefix can also contain simple functor applications (as in the syntactic class extended-module-path above), in case the defining module is the result of a functor application.
Label names, tag names, method names and instance variable names need not be qualified: the former three are global labels, while the latter are local to a class.

The Geometric primitive package contains all the geometric primitives and supporting data types used in describing their boundaries. A geometric primitive is a geometric object that is not decomposed further into other primitives in the system. This includes curves and surfaces, even though they are composed of curve segments and surface patches, respectively. Those curve segments and surface patches cannot exist outside the context of a primitive.
NOTE: Most geometric primitives are decomposable infinitely many times. Adding a centre point to a line may split that line into two separate lines. A new curve drawn across a surface may divide that surface into two parts, each of which is a surface. This is the reason that the normal definition of primitive as "non-decomposable" is not plausible in a geometry model - the only non-decomposable object in geometry is a point.
Any geometric object that is used to describe a feature is a collection of geometric primitives. A collection of geometric primitives may or may not be a geometric complex. Geometric complexes have additional properties such as closure by boundary operations and mutually exclusive component parts. {@link org.opengis.geometry.primitive.Primitive} and {@link org.opengis.geometry.complex.Complex} share most semantics, in the meaning of operations and attributes. There is an exception in that a {@link org.opengis.geometry.primitive.Primitive} shall not contain its boundary (except in the trivial case of {@link org.opengis.geometry.primitive.Point} where the boundary is empty), while a {@link org.opengis.geometry.complex.Complex} shall contain its boundary in all cases.
