I used a simplified method here, but it was code simplification or the sub-governance recursion idea. One is divided into 4, until 2*2 can be solved directly.
The placement of the four dominoes exactly corresponds to: dir [4] [2] = {0, 0}, {0, 1}, {1, 1}, {1, 0 }}; these four directions.
The four directions can be used to determine the four directions of the incomplete position (top left, top right, bottom right, and bottom left ).
Therefore, we can u
