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 is fun to use the powerful computing power of

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

Introduced The Sudoku may only be populated with partial numbers, in which the missing digits are used. Said. Attention matters A valid Sudoku (only partially populated) is not necessarily solvable. 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
