Advent-of-Code-2021

My solution for the advent of code 2021, written in Rust

Error Handle

NOPE!!! unwrap() everything everywhere

Use

To run all of the advent of code solutions

cargo run --release

To run only a specific day (replace {DAY_NUMBER} with the number of that day)

cargo run --release -- {DAY_NUMBER}

Performance

These timing was done on my shitty $5 VPS

Note

• Day 15 part 2: yep, 1 hour and 20 minutes Well, its execution time is now under 200 milliseconds...
• Day 17 part 2: Brute forced it, computer's problems require programming solutions
• Day 19: I calculate the beacons and scanners location while parsing the input since it does not require the full input to be done, that's why the execution time are fast but the parsing is not

Dependencies

• humantime - to display the running time
• owo-colors - to print colored result in terminal
