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 judged to be legitimate.Using Python's expression derivation, anonymous functions and all functions can be easily processed.
