        # Advent of Code [![checks-badge]][checks-link] [![docs-badge]][docs-link]

Complete 2024 to 2015 entries written in Rust for the annual [Advent of Code] challenge,

solving 500 stars in less than 1 second.

## Features

* Each solution uses the most efficient algorithms to the best of my knowledge.

* Self contained depending only on the `std` Rust library. No use of `unsafe` features.

* Consistently formatted with `rustfmt` and linted by `clippy`.

* Thoroughly commented with `rustdoc` generated [documentation online][docs-link].

* Test coverage with continuous integration provided by [GitHub Actions][checks-link].

## Quickstart

Show details


**Input**

Place input files in `input/yearYYYY/dayDD.txt` including leading zeroes. For example:

* `input/year2015/day23.txt`

* `input/year2023/day02.txt`

**Run**

* Everything `cargo run`

* Specific year `cargo run year2023`

* Specific day `cargo run year2023::day01`

* Release profile (faster) `cargo run --release`

* Optimized for current CPU architecture (fastest) `RUSTFLAGS="-C target-cpu=native" cargo run --release`

**Test**

* Everything `cargo test`

* Specific year `cargo test year2023`

* Specific day `cargo test year2023::day01`

* Show STDOUT for debugging `cargo test -- --nocapture`

**Benchmark**

* Everything `cargo bench`

* Specific year `cargo bench year2023`

* Specific day `cargo bench year2023::day01`

**Document**

* Build docs including private items `cargo doc --document-private-items`

* Build doc then open HTML landing page `cargo doc --document-private-items --open`

**Miscellaneous**

* Code quality lints `cargo clippy`

* Consistent code formatting `cargo fmt`

## Performance

Benchmarks are measured using the built-in `cargo bench` tool run on an [Apple M2 Max][apple-link].

All 250 solutions from 2024 to 2015 complete sequentially in **585 milliseconds**.

Interestingly 84% of the total time is spent on just 9 solutions.

Performance is reasonable even on older hardware, for example a 2011 MacBook Pro with an

[Intel i7-2720QM][intel-link] processor takes 3.5 seconds to run the same 225 solutions.
