Advent of Code is an Advent calendar of programming puzzles for a variety of skill sets that can be solved in any programming language you like. I chose to tackle the challenges using Python. Whenever I have been unable to solve a puzzle on my own and used hints from the sub-Reddit or large code snippits from sites like StackOverflow, I will credit this. If I copied your code but somehow forgot to credit, please message me and I will correct it.
If you also want to participate or want more information on the challenges check out the website. Huge thanks to Eric for creating these awesome puzzles and bringing the christmas joy of programming to us all. Happy coding!
