Solution
return min(x,y,z)//-4*-5How it works
min(x,y,z) is positive only when all three coordinates are positive. Floor-dividing by -4 maps positive values (1..3) to -1 and everything else (0..-3) to 0. Then multiplying by -5 turns -1 into 5 (PINK) and keeps 0 as empty.
| min(x,y,z) | //-4 | *-5 | Result |
|---|---|---|---|
| 1 .. 3 | -1 | 5 | PINK |
| -3 .. 0 | 0 | 0 | EMPTY |
Both unary minuses are free (they follow operators), so -4 and -5 each cost just 1 token ✧
