CPP code that asks for the unsolved sudoku matrix and prints the solved matrix using Backtracking. It also tells if the given problem has any solution or not.

CPP code that asks for the unsolved sudoku matrix and prints the solved matrix using Backtracking. It also tells if the given problem has any solution or not.

 

The code checks for every solution possible of the given matrix and checks is that was a correct solution or not.

 

If that was the correct solution, the code prints the matrix but if it isn't, the code proceeds to the next likely solution to be valid and so on.
