My solutions for the Advent of Code 2024 puzzles, in Rust

Usage

1. The application expects your input files to be in the ./input/2024 directory. Each file must be named according to the day number: 01.txt, .. 25.txt.
2. There is only one binary to compile, that invokes all the daily puzzles in sequence (see ./src/main.rs )

Performance

I focus on code readability and usability first, instead of seeking for performance at all cost. As such, this code is well documented and should be very understandable. Here are the results I get to solve the two parts of the problems:

All benchmarks are run on an AMD Ryzen 9 5900X, single thread
