couldn’t understand why are we backtracking outside the for loop, why not after the if loop?
Backtrack outside for loop
hey @devastateddreamer, we backtrack here only when we check all possible combinations for current cell and if we are not finding any correct number for given i,j than make the cell 0 and return false.
If we get correct number for the cell i,j then program control had never reach this backtracking step and return true already.
