sudoku python code

Python implements the code for solving the sudoku program. I accidentally found that a Sudoku game came along with the linux system and played a few games. Instead, I was a Sudoku cainiao. I had never played it before, and I had to make a mess in a few steps. Therefore, it i

How does Python determine whether a Sudoku is valid? Introduction This Sudoku may only contain some numbers, and the missing numbers are represented. Notes A legal Sudoku (partial filling only) is not always solvable. We only need to make the filled space valid. Disintegration ideas Pre-process the

We just need to make the padding space valid. Thoughts of disintegration The Sudoku is preprocessed according to rows, columns, and blocks, and then separately j

This article shares the code of the small program for solving the problem of Sudoku. I used Java to write a small program for solving the problem of 9x9 sudoku. I used the exhaustive method to solve the problem. The code is as follows: Package Test; public class SensibleGame {/*** @ param args */int [] [] mainNumber;
