Advent of Code 2021

To use this, place your puzzle inputs under the inputs directory named day01.txt to day25.txt. To solve the puzzles, simply execute the aoc.py file and it will sequentially solve each day that has a solution given. To test the sample inputs you can run pytest on this project directory to execute all of the tests under the tests directory. Helper functions are under the utils directory, the solutions are under the solutions directory. If you want to only execute a single day you can pass in the --day flag with the day you want to run and optionally use the --override flag to use a different file for overriding the puzzle input for that day.
