Rust 2024 with a single Cargo package.

Rust solutions live under src/bin/${day}_${part}. Each puzzle folder contains its main.rs, main_tests.rs, and local input.txt.

Operation	Command
Initialize part 1	./init.sh ${day} 1
Initialize part 2	./init.sh ${day} 2
Run latest solution	./start.sh
Run selected solution	./start.sh ${day}_${part}
Run selected solution in release mode	./start.sh ${day}_${part} --prod
Test latest solution	./test.sh
Test selected solution	./test.sh ${day}_${part}
Clean build output	./cleanup.sh

• ${day}: number from 01 to 25 (or actual latest). Padded to 2 decimal places.
• ${part}: 1 or 2 depending on what part do you want to check.

Examples:

./init.sh 2 1
./init.sh 2 2
