Recursion Sudoko Solver

In this, we are checking subgrid but not checking row and column. There may be a chance that subgrid is ok but it is repeating in row or column ??

#2

@ashwani225 watch carefully we are iterating in every row and column and checking all the three things row column and subgrid

#3

Yes Ok but if we are checking in row and col then why it is necessary to check for subgrid??

#4

its the property of sudoku each element in row column and subgrid of size root n into root n should be different @ashwani225
