Problem Description

In this problem you need to make a multiply table of N * N ,just like the sample out. The element in the i ^th row and j ^th column should be the product(乘积) of i and j.

 

Input

The first line of input is an integer C which indicate the number of test cases.

Then C test cases follow.Each test case contains an integer N (1<=N<=9) in a line which mentioned above.

 

Output

For each test case, print out the multiply table.

 

Sample Input

  

   2
1
4
  

 

Sample Output

  

   1
1 2 3 4
2 4 6 8
3 6 9 12
4 8 12 16


   

    

     Hint
    
There is no blank space at the end of each line.

			for(j = 1; j <= n; j++)
			{
				printf("%d", i*j);
				if(j == n)
					printf("\n");
				else
					printf(" ");
