advent-of-code-2021 VS advent-of-code-rust

Some very interesting advent of code contributions written in Rust, available on github, use bitwise operations. Shout out to Tim Visee! https://github.com/timvisee/advent-of-code-2021/blob/master/...

This may be the closest thing I've personally seen: https://github.com/timvisee/advent-of-code-2021

Part 2 0.022ms (22μs)

Part 1 1.05ms

Part 1 0.861ms (861μs)

See https://github.com/timvisee/advent-of-code-2021/blob/master/runner/src/bin/bench.rs

Part 1 0.0027ms (2.7μs)

The orientation calculation could be done by matrix indexes operations https://github.com/FlakM/aoc2021/blob/main/day5/task1/src/main.rs and then its easier to create ranges. You can also use some clever crates and get some calculations for free https://github.com/timvisee/advent-of-code-2021/blob/master/day05b/src/main.rs

It's Christmas time and time for Advent of Code 2023 edition. Starting from today I will try to solve puzzles in Rust and publish a post a day in which I tell my solution. My goal is not to climb the leaderboard but to use the problems to practice writing Rust code and improve my language knowledge. Copilot yes or Copilot not? It's for learning so Copilot definitely not. The solutions will be available at the following git repository, as I don't have much time to write a template from scratch, I will use the starter template available here.

If you haven't tried Rust:

Someone put together a very nice template in Rust that automatically downloads tests, solutions, creates a scaffold for the binaries, etc and submits solutions through CLI. I used this template last year to learn Rust and it got me "up and running" quickly and easily.

18. 👨👴 Advent of Code is a yearly event where you can solve small (but high-quality) programming puzzles in any language you want. It can be applied to any language that you are learning. You might find this, this, and this repo useful as well where they provide templates and solutions for prior years.

I know you mentioned you were using this an exercise to learn macros so feel free to ignore this, but I like using this template repository for Advent of Code. It treats each day as a separate binary, but main.rs will run through all the days.

I'm using this template. If you are familiar with Rust you could try running my code in this template to see what speeds you get. This is with the --release flag.

Great solve! Mine ended up being much more complicated since I tired to predict the part 2... Can recommend using a template so you dont have to repeat the whole cargo things, I use this one that builds templates, test and downloads input etc https://github.com/fspoettel/advent-of-code-rust
