I am working on a custom game engine and have been fleshing out the various submodules (meshes, physics, shading, etc.) Here is a sandbox program that exercises the newly finished camera system. After much testing, the camera system will be integrated into the rest of the engine. This program l...

How could I further optimize my implementation of Conway's Game of Life? And how would you critique my current strategies? I'm taking a C++ optimization class, the deadline has passed and my assignment has already been submitted. We were supposed to compile with these options: g++ me.cpp -std=c++...

This code relies on Python3.7.4 I have implemented code for HashMap. It works well. But if you think something needs to be improved, say it. class Hashtable: def __init__(self,size): self.size = size self.mainList = [[] for i in range(0,1)for j in range(self.size)] def ...

So, purely out of desire to learn, I decided to take on a project of making my own very basic programming language from scratch. After which, I made a lexer. I've tested the lexer (but only a bit) and it seems to work. But, I tend to doubt myself a lot (which might actually be a good thing). So...

My approach was to visit all inversion count pair and count how many subarrays these pair contribute. but visiting every pair requires O(n*n) time, but I want an optimized version of this. something like O(nlogn). Can I do something with the Fenwick tree? e.g. if arr = [1,3,4,2] , then total inv...

Recently I was going through some of the solutions of best competitive programmers in the world and I found out that those people use a template while writing the programmes in a particular language preferably in C++. I use C Programming language to write programs and will soon migrate to C++. ...
