I have been programming for a long time. Only recently have I decided to take a stab at python (I should be working with C# as I am in school for it, but I don't care for windows. Long story)
Anyway I was on this site and it showed source for a calculator. I took it, and put it in PyCharm and st...
I was in a code review today and someone said, "Why don't you do an enum on that?" I had started to, but conforming to a bunch of protocols seemed like a gigantic PITA and it seemed more error prone than just writing something simple, readable, and maintainable.
That said, I started to fiddle ar...

A few days ago, I was looking at some code which happened to use a flat array to store a complete binary tree. That got me thinking about calculating some properties of such a tree. The number of no...

I wrote a non-cryptographic hash function in C, which I am hoping might be suitable for use in an implementation of hash sets or hash maps.
uint_fast32_t hash_u32(uint_fast32_t x) {
uint_fast32_t h = x;
h = h ^ (h>>16);
h = h * 0xae6a495b;
h = h ^ (h<<16);
h = h * 0xae6a495b;...
Given a root of a Binary Search Tree (BST) and a number num, implement
an efficient function findLargestSmallerKey that finds the largest key
in the tree that is smaller than num. If such a number doesn’t exist,
return -1. Assume that all keys in the tree are nonnegative.
The Bst Class...
I have written the below code for a color and font checker on a webpage.

I want to create a class that holds a dictionary of <int,int>. This dictionary contains an itemId and the amount of this item.
Let's say there are 50 existing items and this class initializes the dictionary with zero values. It should be possible to setup some initial values and "merge" them to ...

A couple of years ago I wrote a serialisation library for my project. By the time it worked well, but recently I thought it could be modernised. Back then I needed something that looks similar to Boost's serialiser, but also support polymorphism. I need to serialise and deserialise different type...

I am a fan of f"{strings}" in Python,
However some situations could possibly be dangerous when doing f strings from user input, leaking API keys or even code execution!
So I decided to make something to mitigate these attacks. It works by searching with regex over the input string, and will ret...
I am attempting to download all images from multiple websites using BeautifulSoup. I am not able to figure out how to loop through each URL. Additionally, I would like to have these images saved to individual folders for easy identification of the source URL. For example, there were 10 picture...
So I've been messing around with arrays as I'm learning them currently in my book and they gave the idea of a chess board using for loops alongside multidimensional arrays to give them individual values which you can therefore print out.
However, I thought of the old console RPG games from way b...

I needed a reference counted smart pointer for my project, and for some reason early in my project, I decided that I did not like the std::shared_ptr. I can't remember the exact reasons why, but I do remember there was a reason for it. It fell short in some area, but for the life of me I can't re...
