To play, go to the lib/ folder and solve challenges in the day*.ex modules.
To test your solutions, run mix test. The example inputs have been added to the tests for your convenience.
If you want to compete on the Advent of Code leaderboard, use the code 25717-bb9d6ba6.
Running mix day X part Y will also run your solutions against input files, if provided.
You can run all of your solutions with mix day.
For each day, put a file named dayX.txt into the priv/inputs folder. For example, for day 10, the file would be at priv/inputs/day10.txt.
