Advent of Code 2022

My solutions to the Advent of Code 2022 puzzles, written in Rust.

Goals

My main goal is not to create the quickest / shortest / fastest solution ever, but to create nice, idiomatic, readable and maintainable Rust code with suitable performance.

Each day's puzzle solver is implemented in a separate binary. All puzzle solvers are developed in a test-driven approach, i.e. examples from puzzle descriptions are used in unit tests to verify correct implementation (cargo test). Running a solver uses the (personalized) puzzle input to find the solution (cargo run).
