Seek Sudoku, only ask to make an answer.Just beginning to understand test instructions wrong, think the answer is unique, so did not do it for a long time, found that the answer is not unique after using backtracking. (or a reference to others)public class Solution {public void Solvesudoku (char[][] board) {hashset[] HashSet = new Hashset[27];for (int i = 0; I Backtracking is still relatively simple, that is, in the implementation of the time, if you

The implementation of this algorithm is to simulate the thinking and computing process of the human brain. If you need it, you can refer to it. 1) when we get a question, we will first follow the conditions we already know, sort and analyze the data. It is equivalent to writing all "OK items" in the 9th Palace, and marking "Possible options ". Function refreshStat () 2) afterwards, the thinking will enter the cycle of speculation/verification. In cells 9, you can try "Possible options" to verif

Test instructionsGive you a 9*9 matrix that separates the two elements adjacent to the same row with a single space. Where 1-9 represents the already filled number of the position, the question mark (?) indicates the number you want to fill. The solution of this Sudoku is output and there is only one solution for each group.Ideas:Record the vacant place, each vacant place has 9 in the state, DFS + pruning processing other, with scanf input, get () tle
