Problem Description

There are four matrixs blow , Can you image the NEXT matrix from the given information?

Input

The first line is a integer which represents the case number .
For each test case , there will be a line which contains a integer N (1<=N<=100).

Output

Output the matrix which has N*N integers. Be careful that there is a blank space between two
integer but no blank space after the last integer in a line.

Sample Input

4 1 2 3 4

Sample Output

1 1 2 4 3 1 2 3 8 7 4 9 6 5 1 2 3 4 12 11 10 5 13 14 9 6 16 15 8 7

AC代碼：

#include<iostream>
using namespace std;
int p[100][100];

int main()
{
int n,i,j,k,x,y,t;
cin>>t;
while(t--)
{
?cin>>n;
?k=0;
?x=0;
?if(n==1) cout<<1<<endl;
