I have built a Blackjack simulator in python. I need to increase execution time performance. I have used a profiler to identify key influencers in execution time.
The following function is responsible for about 15% of the total run time.

I am practicing coding questions on leetcode. I have been an OOP my whole career, and I am trying to wade into the dark abyss that is functional programming. So I am trying to do things purely functional, e.g. using recursion to try to get to the answer. The problem statement is this: Given a str...

BitmapData data = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, PixelFormat.Format1bppIndexed);

What would be the better approach from a readability point of view:
X = $(cat sample | wc -l)
(which some may argue that is a useless cat usage, but there is a difference between counting the stdin versus a file)
alternatives would be:
X = $(wc -l sample | cut -f1)
or even:
X = $(wc -l sa...
I have created a fractal tree based on the Lindmayer System in Python. If you could tell me about any algorithmic or efficiency-based problems in the code, I would be grateful.

Inspired by this answer on stackoverflow for AI implementation in 2048 game.
I have been trying to make AI calculate best move by playing the game given specific times in memory preceding by one specific move first, then averaging the score and declaring move with highest score as best move.

I'm looking for some feedback on this code I wrote tackling a general solution to the age old "Add 2 numbers represented by Linked Lists". This specific one aims to be able to sum any given number of linked lists.
Ofcourse, the input linked lists must contain the number in reverse order.

I wrote a simple algorithm to encrypt and decrypt files in Python using aes-256-cbc.

While rewriting Array so I can practice my javascript, I looked at my implementation of .join(). It seems a little clunky to me.
I've tried to cover all the edges, like making sure separator isn't null before joining, not adding the separator at the end of the string, and writing some documentat...
