Welcome everyone to the 2023 advent of code! Thank you all for stopping by and participating in it in programming.dev whether youre new to the event or doing it again.
This is an unofficial community for the event as no official spot exists on lemmy but ill be running it as best I can with Sigmatics modding as well. Ill be running a solution megathread every day where you can share solutions with other participants to compare your answers and to see the things other people come up with
Day 1: Trebuchet?!
Megathread guidelines
- Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
- Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ or pastebin (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

Ive been trying to learn rust for like a month now and I figured I’d try aoc with rust instead of typescript. Your solution is way better than mine and also pretty incomprehensible to me lol. I suck at rust -_-
In case that this might help.
h.chars() returns an iterator of characters. Then he concatenate chars and see if it's a digit or a number string.
You can swap match u.is_numeric() with if u.is_numeric and covert _ => branch to else.
