Quest 3: The Deepest Fit

• 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)
• You can send code in code blocks by using three backticks, the code, and then three backticks or use something such as https://topaz.github.io/paste/ if you prefer sending it through a URL

Uiua

I'm currently going through the 2025 Quests to learn Rust, committing great sins along the way.
Decided to take a shot at the third one with Uiua because it looked nice and simple, and it was. This may have been the fastest I've ever finished a complete quest :P
