CF1512B Almost Rectangle

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.

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.

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.
