This is my personal repo for Advent of Code 2024 solutions.
I used this year as a chance to brush up on my Kotlin. Though the AOC challenges aren't always the perfect demonstration for many Kotlin features -- which shine most in larger codebases with asynchronous work -- it was definitely an interesting, fun, and fairly efficient way to solve these challenges.
You can find the code for each day under app/src/main/kotlin, with unit tests in
the corresponding directories under app/src/test/kotlin. Keep in mind that some of
the code does contain spoilers for the solutions!
The runtimes for each day are listed below (parts 1 & 2 combined, as measured on my computer):
