You are given a rectangular cuboid of size W (width), H (height) and D (depth) consisting of W * H * D cubes. The top row (layer) of the cube is considered to be with height 0. Each cube can contain one of the following things – slide, teleport, basket or just be an empty cube. A small ball that can fit through a single cube is dropped over the …
