Anti-Sudoku
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 $$$1 \le i, j \le 9$$$ 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.
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.
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.
t = ''
for s in [*open(0)][1:]:
    t += s.replace('1', '2')
print(t)
t = ''
for s in [*open(0)][1:]:
    t += s.replace('1', '2') + '\n'
print(t)
for t in [*open(0)][1:]:
    print(t.replace('1', '2'))
