🎄advent-of-code-2022

Overview

This repository contains my solutions to Advent of Code 2022.

I decided to take this year as an opportunity to learn Rust. My goal will be to write simple, readable, and idiomatic Rust code as much as I can. I will be restricting myself to the standard library and try to get familiar with it.

I will also try to add basic comments explaining my approach, as well as benchmark the code.

Note - This is my first time writing Rust programs. For many of my solutions there might be a better way, in terms of efficiency or writing Rust-y code.

Solutions

All common utility stuff is defined in the src/lib.rs file. Solutions for day XY are defined in the src/solvers/day_XY.rs file. Inputs for day XY are in the inputs/XY.txt and inputs/XY_test.txt (which is the sample input).

Note:

• The solutions and tests been checked with Cargo & Rust v1.65.0.
• The benchmarks been checked with Cargo & Rust v1.67.0-nightly.

Run

# Running all solutions
$ cargo run --release -- all
# Running a particular solution
$ cargo run --release -- run <day> [part] # day = XY, part = a / b (optional, runs both parts by default)

Test

Sample input for each day has been used to write unit tests.

# Testing all sample inputs
$ cargo test
# Testing sample input for particular day
$ cargo test XY

Benchmarks

Note: This requires features from the unstable release chain, which can be installed using -

$ rustup install nightly

Once nightly rust has been installed

# Running all benchmarks
$ cargo +nightly bench
# Running benchmarks for particular day
$ cargo +nightly bench XY
