How to use C++ to realize horse pedal chessboard

This article mainly introduces how to use C++ to achieve horse chessboard, the article is very detailed, has a certain reference value, interested friends must finish!

The horse stepped on the chessboard and walked all over the chessboard with one horse. I use a two-dimensional array to record the entire path of the simulation, x as the column, y as the row, to find the next grid clockwise, the algorithm is relatively simple, through recursion and circular backtracking, that is, if it is an array of 8 to 8, the worst possible execution is 8 ^ (xroomy) times, which takes a long time to doubt life.
