Advent of Code 2021-2022

My solutions for Advent of Code 2021 and 2022

Build and run

Run the exercises using cargo:

cargo run run example for the today's date (only makes sense in advent)
cargo run -- <day> run example for the specified day in the current year
cargo run -- <day> <year> run example for the specified day in the current year

The --answer option that must come last will compute the actual result for the specified date (not just the example).

Tests

Most exercise programs and utility routines contain a number of unit tests to verify correctness. Run them using cargo test.
