rDrama Advent of Code Day 6 Discussion Thread

Not sure where @RedNose is so I'll just post this. Post ur solutions below or whatever idc

Advent of Code is an annual Christmas themed coding challenge that runs from December 1st until christmas. Each day the coding problems get progressively harder. We have a leaderboard and pretty good turnout, so feel free to hop in at any time and show your stuff!

Whether you have a single line monstrosity or a beautiful phone book sized stack of OOP code, you can export it in a nice little image for sharing at https://carbon.vercel.app

What genius put the range-splitting question on day 5 and this on day 6?

s←⍎¨r←11∘↓¨⊃⎕NGET'6.in'1
⎕←×/+/¨(2⊃s)<(⊢×⌽)¨⍳¨-∘1⊃s
t d←⍎¨~∘' '¨r ⋄ ⎕←t-1-⍨2×1∘+⍣{d<⍺×t-⍺}⊢1

Or if you wanna be a nerd and use quadratics:

q←{⌈1E¯10+¯2÷⍨(¯1×⍵)+(*∘0.5)(¯4×⍺)+⍵*2}
⎕←×/1+(⊃s)-2×(2∘⊃q¨⊃)s
⎕←t-1-⍨2×d q t
