P7554 [CF1512B] Almost Rectangle
入门
题目描述

There is a square field of size $n \times n$ in which two cells are marked. These cells can be in the same row or column.

You are to mark two more cells so that they are the corners of a rectangle with sides parallel to the coordinate axes.

For example, if $n=4$ and a rectangular field looks like this (there are asterisks in the marked cells):

$$ \begin{matrix} . & . & * & . \\ . & . & . & . \\ * & . & . & . \\ . & . & . & . \\ \end{matrix} $$

Then you can mark two more cells as follows

$$ \begin{matrix} * & . & * & . \\ . & . & . & . \\ * & . & * & . \\ . & . & . & . \\ \end{matrix} $$

If there are several possible solutions, then print any of them.

Input

The first line contains a single integer $t$ ($1 \le t \le 400$). Then $t$ test cases follow.

The first row of each test case contains a single integer $n$ ($2 \le n \le 400$) — the number of rows and columns in the table.

The following $n$ lines each contain $n$ characters '.' or '*' denoting empty and marked cells, respectively.

It is guaranteed that the sums of $n$ for all test cases do not exceed $400$.

It is guaranteed that there are exactly two asterisks on the field. They can be in the same row/column.

It is guaranteed that the solution exists.

Output

For each test case, output $n$ rows of $n$ characters — a field with four asterisks marked corresponding to the statements. If there multiple correct answers, print any of them.
