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

#include 
      
        int main( ) {
     int N, T;     scanf("%d", &T); while(T--) {
             scanf("%d", &N); int i, j, flag = 0; for(i = 1; i <= N; i++) {
     for(j = 1; j <= N; j++) {
     if (!flag)                 printf("%d",i * j), flag = 1; else                 printf(" %d",i *j);             }             flag = 0;             puts("");         }     } return 0; }
