Special Judge
Sudoku is a very simple task. A square
table with 9 rows and 9 columns is divided to 9 smaller squares 3x3 as
shown on the Figure. In some of the cells are written decimal digits
from 1 to 9. The other cells are empty. The goal is to fill the empty
cells with decimal digits from 1 to 9, one digit per cell, in such way
that in each row, in each column and in each marked 3x3 subsquare, all
the digits from 1 to 9 to appear. Write a program to solve a given
Sudoku-task.
Input
The input data will start with the number
of the test cases. For each test case, 9 lines follow, corresponding to
the rows of the table. On each line a string of exactly 9 decimal digits
is given, corresponding to the cells in this line. If a cell is empty
it is represented by 0.
Output
For each test case your program should
print the solution in the same format as the input data. The empty cells
have to be filled according to the rules. If solutions is not unique,
then the program may print any one of them.
