题目描述
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](http://tiny.cc/636xmz).
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 $1 \le i, j \le 9$ 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 $9 \times 9$ field, in which:
- Any number in this field is in range $[1; 9]$ ;
- each row contains at least two equal elements;
- each column contains at least two equal elements;
- each $3 \times 3$ block (you can read what is the block in the link above) contains at least two equal elements.
It is guaranteed that the answer exists.
You have to answer $t$ independent test cases.

输入格式
The first line of the input contains one integer $t$ ( $1 \le t \le 10^4$ ) — 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.
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.
输出格式
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.
