To run a solution:

$ iex -S mix

AdventOfCode2024.run(1) # <= day
# {:ok, 22_588_371}

Each day challenge has 2 parts, so for each part, we have a specific commit and tag, that you can use to execute the specific day/part you want, like:

$ git checkout day_1_1st_solution

AdventOfCode2024.run(1) # <= day
# {:ok, 1_590_491}
