Rectangular chocolate bar Create at least one piece which consists of exactly nTiles tiles

Rectangular chocolate bar Create at least one piece which consists of exactly nTiles tiles.

You have a rectangular chocolate bar that consists of width x height square tiles. You can split it into two rectangular pieces by creating a single vertical or horizontal break along tile edges. For example, a 2x2 chocolate bar can be divided into two 2x1 pieces, but it cannot be divided into two pieces, where one of them is 1x1. You can repeat the split operation as many times as you want, each time splitting a single rectangular piece into two rectangular pieces.
