Given an incomplete Sudoku configuration in terms of a 9 x 9 2-D square matrix (mat). The task to print a solved Sudoku. For simplicity you may assume that there will be only one unique solution.
Sample Sudoku for you to get the logic for its solution:
The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains 9*9 space separated values of the matrix mat representing an incomplete Sudoku state where a 0 represents empty block.
For each test case, in a new line, print the space separated values of the solution of the the sudoku.
