Coral (Skyscrapers)
(Published on 7. April 2025, 02:14 by KNT)
A coral is to be drawn in the grid: the coral is orthogonally connected, contains no 2x2 area, and does not 'lock in' any cells; that is, all orthogonally connected groups of non-coral cells are orthogonally connected to the boundary.
Numbers outside the grid show the number of separate coral segments visible in that direction. A segment is considered visible if all segments in front of it are of smaller length.
