Problem Description

In this problem you need to make a multiply table of N * N ,just like the sample out. The element in the ith row and jth 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

就是输入t个数，对于每个数n，输出n*n个数。

i为1-n，j为1-n，输出i*j。

每一行最后一个输出后面没有空格啊！！！

import java.util.Scanner;

public class Main{

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int t =sc.nextInt();

        while(t-->0){

            int n =sc.nextInt();

            for(int i=1;i<=n;i++){

                for(int j=1;j<=n;j++){

                    if(j==1){

                        System.out.print(i*j);

                    }else{

                        System.out.print(" "+i*j);

                    }

                }

                System.out.println();

            }

        }

    }

}
