Remember that a Sudoku is a game that consists of completing a grid with numbers between 1 and 9, so that the final result has not repeated numbers in the same row, column or submatrix. For example, this is a Sudoku and its solution:
(9,9) (0,0)(0,9) (1,0)(1,9) (2,0)(2,9) (3,0)(3,9) (4,0)(4,9) (5,0)(5,9) (6,0)(6,9) (7,0)(7,9) (8,0)(8,9) (9,0)(9,9)
(0,0)(9,0) (0,1)(9,1) (0,2)(9,2) (0,3)(9,3) (0,4)(9,4) (0,5)(9,5) (0,6)(9,6) (0,7)(9,7) (0,8)(9,8) (0,9)(9,9)

In this problem we do not ask you to solve any Sudoku, just to check that every given matrix can be the solution of a Sudoku.
Input consists of a number , followed by cases. Every case has 9 rows, each one with 9 numbers between 1 and 9.
For every case, print “yes” or “no”
depending on whether the given matrix follows the rules of the solutions
of Sudokus.
Input
