Advent of Code 2024 in Go

Each day is its own subdirectory, in the file main.go. Usually, the input for the day will be in a file called input.txt. Additionally, the example data is usually in a file called testdata/example.txt and is referenced from the unit tests.

There is also a set of common utility functions and types in the common package.

There is a command leaderboard.go to print out the time it took everyone on a private leaderboard to get the first and second part of a particular day.

Usage of leaderboard.go:
  -day int
    	day to display, or most recent if not provided
  -endpoint string
    	URL of the leaderboard JSON endpoint. Can also set the LEADERBOARD_URL env variable.
  -session string
    	session cookie value. Can also set the LEADERBOARD_SESSION env variable.

Example:

$ go run leaderboard.go -day 3 -endpoint https://adventofcode.com/2024/leaderboard/private/view/123456.json -session 53616c7465645f5f89e40247fe925752de8a696d76c2f03f361ed6ea24283
