B"You are given a correct solution of the sudoku puzzle. If you don't know what is the sudoku, you can read about it here. The picture showing the correct sudoku solution: Blocks are bordered with bold black color. Your task is to change at most 9 elements of this field (i.e. choose some 1 <= i, j <= 9 and change the number at the position (i, j) to any other number in range [1; 9] ) to make it anti-sudoku. The anti-sudoku is the 9 x 9 field, in which: It is guaranteed that the answer exists. You have to answer t independent test cases. The first line of the input contains one integer t ( 1 <= t <= 10^4 ) -- the number of test cases. Then t test cases follow. Each test case consists of 9 lines, each line consists of 9 characters from 1 to 9 without any whitespaces -- the correct solution of the sudoku puzzle. For each test case, print the answer -- the initial field with at most 9 changed elements so that the obtained field is anti-sudoku. If there are several solutions, you can print any. It is guaranteed that the answer exists. "...
