Problem statement

You are given an integer ‘N’, ‘N’ will always be an odd integer. Your task is to print a pattern with the following description:

1. The pattern will consist of ‘N’ lines.
2. The pattern will consist of ‘ ‘ (space) and ‘*’ characters only.
3. The pattern will be a “Void of Diamond” pattern.
4. A “Void of Diamond” pattern is a pattern ‘N’ * ‘N’ cells and ‘ ‘ characters make a diamond shape and ‘*’ fill all other points.
5. For a better understanding of the “Void of Diamond” pattern refer to example and sample input-output.

For example:

If ‘N’ is 5 then the pattern will be-

*****
** **
*   *
** **
*****

Detailed explanation ( Input/output format, Notes, Images )

Input Format:

The first line of input contains an integer 'T' representing the number of test cases.

Then each test case contains a single integer ‘N’ denoting the size of the pattern.

Output Format:

For each test case, print 'N' strings denoting the pattern.

The output of each test case will be printed in a separate line.

Constraints:

1 <= T <= 5
3 <= N <= 500

Where ‘T’ is the number of test cases, ‘N’  is the size of the pattern. ‘N’ will be odd for all test cases.

Note:

You do not need to print anything, it has already been taken care of. Just implement the given function.

Sample Input 1:

2
5
3

Sample Output 1:

*****
** **
*   *
** **
*****
***
* *
***

Explanation of Sample Input 1:

Test Case 1:

Given ‘N’ = 5
We will print the pattern as the description of the “Void of Diamond” pattern.

Test Case 2:

Given ‘N’ = 3
There will be only 1 ‘ ‘ space in the diamond pattern.

Sample Input 2:

2
7
9

Sample Output 2:

*******
*** ***
**   **
*     *
**   **
*** ***
*******
*********
**** ****
***   ***
**     **
*       *
**     **
***   ***
**** ****
*********

Explanation of Sample Input 2:

Test Case 1:

Given ‘N' = 7
The pattern is printed such that ‘ ‘ making a diamond and ‘*’ filling other points.

Test Case 2:

Given ‘N’ = 9
Created a 9*9 grid and all space cells make a diamond pattern.
