    Pretty much just a transcription of my Dart solution.

      Welp, got frustrated again with part one because there kept being something wrong with my totally-not-ugly loop and so came here again. I did have to change IsInt (and thus also Cost to account for different handling) for part two though because I kept getting wrong results for my input.
      I’m guessing it’s because uiua didn’t see the difference between rounded and non-rounded number anymore.

      Here’s the updated, slightly messier version of the two functions that worked out for me in the end :D

      IsInt ← ≍°⊟⍉⍜(⊙(⍉≡↙₂))(/+×)⊙⍉⁅
Cost  ← /+×3_1×⟜IsInt⊸AB

      Could have been done better but I’m lacking the patience for that now

        Yeah, I had to fiddle with that limit before it actually worked for me, so it’s clearly quite sensitive to the data :-)
