Originally I made each day in a separate folder. All those can be found inside days/
But now I intend to wrap everything in a mix project (aoc/ folder)
The reason for that is that some code could be reused.
So aoc/ contains a utils.ex module for opening inputs, and then one module per day.
Only the first day exists in this aoc/ project for now
cd advent_of_code_2022/days/day1
elixir solution.ex
cd advent_of_code_2022/aox
iex -S mix
iex(1)> One.part_one()
iex(2)> One.part_two()
