I have a string of numbers that look like 999999999.99999 and I would like it to be 999,999,999.99999
Using the below code works but I get commas after the decimal point like this 999,999,999.99,999
var numberstring = 999999999.99999;
numberstring.toString().replace(/\B(?=(\d{3})+(?!\d)(\W))/g,...
I have implemented below code for the topic mentioned. Results are coming incorrect in c++. same code is working correctly in python why?
for (int i = 1; i <1000; i++) {
if (i % three == 0 || i%five==0) {
sum_3 += i;
}
}

I understand that writing "Arrow Code" like above is an anti-pattern.
But then I encountered myself writing similar code when dealing with graphics.
Is there a better way to write the following?

I have been trying to solve this HackerRank problem. What I came up is this
class TrieNode():
def __init__(self):
self.children = {}
self.word_count = 0
class Trie():
def __init__(self):
self.root = self.get_node()
def get_node(self):

I have made a project at Github that uses computer vision to solve Sudokus. Since this is my first project I would really like to get some feedback on my code. Since it is not allowed to link my repository I took one class that I have created. So, I am mostly looking for feedback on how I writ...

I have this long line of code:
enc = encoder.predict(np.array([data[stock][4*i:4*(i+30)] for i in range(lens[stock]+days-30)]))
The problem is, the number of characters (97) exceed 79, which is not allowed by PEP 8. To follow the PEP 8 guideline I can
temp = [data[stock][4*i:4*(i+30)] for i i...
As Leigh Riffel said, the answer to my question depends partially on what you mean by "major."
I'm going with: No, there are no major RDBMS engines out there that can't handle name escaping/quoting. A quoted/escaped name is apparently properly called a delimited identifier.

I am a beginner of Rust language. As my practice I want to create simple train reservation system.
I know little about the "best practice" in Rust, so I want some advises in my code. In terms of the function there are much luck to improve, but I want advises about how to write codes "...

I have found that there is a distinct lack of an RPN calculator available to me, so I decided to make my own. I am still adding new functions to it, but as of now, I would like to refactor my code.

I'm still fairly new to Swift and IOS Development. I have made my first own app, which is an app to save and track fuel consumption. The problem is that I have a lot of problems organizing my code. The logic of my application is fairly simple and lives in its own classes, but my UIViewControllers...

I am new to Python (it's my first language), been coding for a couple of weeks now.

So I have an app that parse XMLTV file into a TV Guide listing, the file is quite big (35MB) with tons of information, right now it takes around 20-30 seconds to parse the file completely!! Which is way too much, any ideas of how to improve it?

I solved the following problem:

Should be more efficient than .OrderBy().Take(n) as it does not keep all items in memory as OrderBy does:
