🎄 Advent of Code 🎄

Advent of Code

Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as interview prep, company training, university coursework, practice problems, a speed contest, or to challenge each other.

How to

All necessary Cargo commands are wrapped in a convenient Makefile. During the event, the make command is especially handy for quickly testing and solving each day's puzzle.

make                          # Test and solve today's puzzle automatically
make new                      # Create boilerplate files for today's DAY and YEAR

make 03                       # Test + solve Day 03 (for current year)
make test DAY=05              # Run only tests for Day 05 (for current year)
make solve YEAR=2023 DAY=14   # Solve Day 14 for Year 2023
make bench YEAR=2024          # Benchmark entire Year

make checks                   # Run clippy and fmt with cargo

Input files are downloaded automatically. To enable this, create a file named adventofcode.session in the project root containing your Advent of Code session cookie. Timings are cargo bench averages measured on an Intel Core i9-13900K.
