What is Advent of Code?
Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.
I'm currently working on the problems in Advent of Code 2021, and considering the fact that you can't upload your codes on their website, I thought it'd be a good idea if I uploaded them on GitHub.
