cargo build
Typical usage for each day's exercise is:
cargo run --bin day_NN -- <PART> [input_file]
Where:
- NN is the day 01, 02, 03, .. 24
- PART is the part of that day's exercise (1 or 2)
- input_file is an optional override of the input data file
Input data files are stored in data. Each day's program will default to
loading data/day_NN.txt (if both parts use the same data) or
data/day_NN_P.txt (if each part has different data)
