the termination of the condition of recursion, to reach the termination conditions, the inspection results are qualified, qualified records down. And the essence of backtracking is in the following for loop, a total of 5 steps, the last two steps is just the first two steps of the anti-operation, and therefore become ' backtracking '. We can argue that backtracking is an optimization of brute force search (brute).A little gossip, to see Sudoku
