It is also a typical problem to find the connected block with DFS, and the process of multi-dimensional array connecting block is also called "seed filling".We add numbers to the connected blocks that are traversed each time, so that you can avoid a lattice access multiple times. The typical problem is the "eight-block problem". That is, any two squares are located adjacent to each other (up and down diagonally a total of eight positions), then in a c
