Starting a new day

There's a script to start a new day:

./new_day.sh <day_number>

Running the script will create a new folder with the template files for a Python solution under python/<day_number> as well as a new file for a Rust solution in rust/src/day_<day_number>.rs.

Running the solutions

For Python:

• Go to the directory of the day you want to run (e.g. cd python/04)
• Run python sol.py to run the solution against your individual input
• ... or run python sol.py X to run the solution against the input stored in the file sX.txt in the same directory

For Rust:

• rustup install nightly (only needed before running anything for the first time)
• cd rust
• cargo +nightly run will run the solution for all days
• cargo +nightly run X will run the solution for day X
• cargo +nightly test will run all tests
• cargo +nightly test X will run tests for day X
• cargo +nightly bench will run all benchmarks
