AdventOfCode2024

Elixir solutions for the 2024 Advent of Code puzzles.

Importing puzzle data

Puzzle data is generated on the AoC website. You need to grab your session cookie and put it into a config/secrets.exs file, after that you can run mix input 1 2024 to get the inputs for day 1 of AoC 2024.

• priv directory - put your puzzle data here with proper name (day_200.txt etc)

Solving a puzzle

• test/examples directory - put your example data here with a proper name (day200.txt etc)
• create an AdventOfCode.Day200 module in lib/advent_of_code/day_200.ex. Needs to have a part1 and an part2 public methods, so that you can use the mix tasks to run them, otherwise it can use whatever you like.
• create a tests/day200_test.exs so that you can run tests:

assert Day200.part2("test/examples/day200.txt") == 12345

Running the puzzle solvers

Use the mix tasks. They both take the module name as an argument:

• mix part1 Day200 solves the part one of the given puzzle using the part1 method
• mix part2 Day200 solves the part two of the given puzzle using the part2 method
