advent-of-code-2022 VS advent

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.

Maybe a bit less neat in the binary sense, but definitely very fast.

Part 2 5.72 ms

I'm using the guy who does "the entire AoC in less than a sceond"'s timing code, so I assume it's kosher

Part 1 0.027ms (27 μs)

No heap allocations: https://github.com/tsenart/advent/blob/master/2023/4

~200 microseconds runtime Go solutions based on BFS that plot the path in the terminal: https://github.com/tsenart/advent/tree/master/2022/12

Nice. I did that but traversing all directions in each inner loop iteration: https://github.com/tsenart/advent/blob/master/2022/8/one.go
