advent_of_code_2021

Solutions for Advent of Code 2021 written in rust.

Some solutions are a bit scuffed, but the overall time to run both part 1 and part 2 for all days takes ~2.3 seconds, which I'm happy with.

Run with:

cargo run --release

To run a specific day:

cargo run --release {day_number}

To run with example input:

cargo run --release {day_number} --example

Note:

• Some days require to be run with --release flag, since they depend on number overflowing, which raises error in development mode.
• Day 13 part 2 output isn't the real solution; uncomment the result printout which will display human readable number, which is the actual solution.
