Advent of Code solutions

Solutions to Advent of Code problems 2021 in Rust.

This repository holds a single Rust project that contains all the days.

Run the solutions

The command line tool takes <day> <part> as arguments and reads the problem input from stdin. To run the solution for the first part of day 1 you can run:

$ cat src/year2021/day01_input.txt | cargo run -q 1 2

Add new solutions

To add a new solution (day), you need to:

• Create a file day01.rs under src/year2021;
• Add a function pub fn solve(input: &mut Input) -> Result<u32, String> under that file;
• Export the function in src/year2021/mod.rs;

git config --local core.hooksPath ./hooks
