Solution
p=x*x q=y*y r=z*z return p|r<4 and(y==2 or y==-2 and 9)or q|r<4 and(x==-2 and 14 or x==2 and 11)or p|q<4 and(z==-2 and 7 or z==2 and 8)or p|q|r>3 and 3How it works
It’s a Rubik’s cube! Black frame with a different color on each face: white on top, yellow on bottom, lightblue/green on the sides, red/orange front and back.
We store x*x, y*y, z*z in p, q, r and then lean hard on bitwise OR to check if coordinates are “small” (within the face center). p|r<4 means both abs(x) and abs(z) are less than 2, so we’re looking at the top/bottom face strip. If y is at the edge (±2), we paint the face color, otherwise the and/or chain moves on.
The top face (y==2) uses the bare-true-as-WHITE trick: since true counts as color 1 in the game, we just let y==2 return true directly instead of writing y==2 and 1. One of our favorite freebies!
The frame itself is anything on the surface (p|q|r>3, meaning at least one coordinate is at the edge) that wasn’t already claimed by a face. All the leftover surface gets painted black.
