Advent of Code

This repo contains my solutions to Advent of Code problems in Rust. It also includes a helper library that I've developed over time, consisting of data structures and functions that have proven useful in solving past problems.

How to run

You need to have rustc (and cargo) installed. Instructions here.

Then for any particular year_day we need to run this command from the root directory

cargo run --release --bin <year_day> <input_file>

For example for binary 2022_01 say we have a sample_input.txt file with the following contents

1000
2000
3000

4000

5000
6000

7000
8000
9000

10000

Then we run

cargo run --release --bin 2022_01 <full path to sample_input.txt>

which outputs the answers for both parts

Part #1 Answer 24000
Time elapsed in Part #1 is: 75µs

Part #2 Answer 41000
Time elapsed in Part #2 is: 5.042µs

Testing

Unit tests are included for some problems using the sample IO. To run tests

cargo test

To test a specific binary only

cargo test --bin 2023_01
