Advent of Code 2022, day 1: Calorie Counting

Setup

file_path = __DIR__ <> "/../../lib/2022/01_calorie_counting/input.txt"

Part 1 and Part 2

{part1, part2} =
  File.read!(file_path)
  |> String.split("\n\n", trim: true)
  |> Enum.map(fn elf ->
    elf |> String.split("\n", trim: true) |> Enum.map(&String.to_integer/1) |> Enum.sum()
  end)
  |> Enum.sort()
  |> Enum.reverse()
  |> then(fn calories -> {hd(calories), calories |> Enum.take(3) |> Enum.sum()} end)

Confirm final result

70_698 = part1
206_643 = part2
"🥳"
