Rosetta code and Project Euler solutions

Programming Challenges

This page is for small little programming challenges I think don't deserve a seperate GitHub page so I've made this repository to store them in one collection.

I've mainly used rosetta code for the challenges but I didn't always follow the specifications since I thought they were stupid or unnecessary. For other challenges I've used project euler and other miscellaneous websites.

I started this repository using only C++ but that got boring quite quickly, So I've decided to add more languages to the list (More to come)

Some of those challenges aren't written very well, So don't use this to study. But I think they are fine for inspiration.

All challenges are public domain.

Here is a list of Project Euler challenges:
