full light

The game rules are very simple. The board of the lighting game is a square grid, and the grids may be black or white. The game goal is to place light bulbs in the grid so that they can illuminate all the white squares. If a grid is located in the same row or column as a light bulb, and there is no black grid blocking between the grid and the light bulb, then the grid will be illuminated by the light bulb. Meanwhile, each placed light bulb cannot be illuminated by another light bulb.
Some black squares are marked with numbers. These numbers indicate how many light bulbs are in the adjacent cells around the grid.
