Thus, we can also conclude that a Sudoku is considered wrongly filled if it satisfies any of these criteria: Any row contains the same number more than once. Any column contains the same number more than once. Any 3x3 sub-matrix has the same number more than once. The steps which we will follow are: If there are no unallocated cells, then the Sudoku is already solved. We will just return true. Or else, we will fill an unallocated cell with a digit between 1 to 9 so that there are no conflicts in any of the rows, columns, or the 3x3 sub-matrices.
Now, we will try to fill the next unallocated cell and if this happens successfully, then we will return true. Else, we will come back and change the digit we used to fill the cell. If there is no digit which fulfills the need, then we will just return false as there is no solution of this Sudoku.
