Problem Statement

#### You are given an integer ‘N’ denoting the given number of rows. Can you print the pattern Ninja wants to create?

##### Pattern for N = 3:
``````*   *
* *
* * *
* *
*   *
``````
##### Input Format:
``````The first line contains ‘T’, denoting the number of test cases.

Each test case contains a single integer ‘N’, denoting the number of rows.
``````
##### Output Format:
``````For each test case, print the 'N' strings denoting the required pattern in the following ‘N’ lines.
``````
##### Note:
``````You are not required to print the expected output; it has already been taken care of. Just implement the function.
``````
##### Constraints:
``````1 <= T <= 10
1 <= N <= 10^3

Time Limit: 1 sec

##### Explanation for Sample Input 1 :
``````In the first test case, we are required to create a pattern consisting of 3 lines. First-line contains ‘A’. From the second line, we have to place a character one more than the previous value. So we place ‘B’.We put 2 ‘B’ and move to the following line because this line will contain only 2 elements. In the following line, we have to place 3 characters, so we place 3 ‘C’.

In the second test case, we are required to create a pattern consisting of 4 lines. First-line contains ‘A’. From the second line, we have to place a character one more than the previous value. So we place ‘B’.We put 2 ‘B’ and move to the following line because this line will contain only 2 elements. In the following line, we have to place 3 characters, so we place 3 ‘C’.In the next line, there will be 4 ‘D’.
