Cell Tower is an interesting daily puzzle game, https://www.andrewt.net/puzzles/cell-tower/. Here we consider a simplified version. You are given 8×8 square with one character in each cell and a dictionary. Please divide the square into several parts, so that each part is a connected block and the characters in this connected block (from top to bottom and from left to right) make up a valid word (i.e., appear in the dictionary).

Two cells A,B are called connected pair, if A and B directly share the same side, or there exists another cell C so that both A,C and B,C are connected pairs.

A group of cells is called connected block if any pair of cells in this group are connected pairs and the size of this group is either 3 or 4.
