Code:

#include <iostream>

using namespace std;

int main(int argc, char** argv)

{

int n,i,j,x=1;

cin>>n;

int m;

int arr[n][n];

for(i=0;i<n/2;i++)

    {

     for(j=0;j<n;j++)

        {

            arr[i][j]=x++;

        }

        x+=n;

    }

    x=1;

    if(n%2==1)

        m=n/2+1;

    else

        m=n/2;

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

{

    if(i>m)

    {

        x=arr[n-i][n-1];

        x++;

    }

    for(j=0;j<n;j++)

    {

        cout<<x++<<" ";

    }

    x+=n;

cout<<"\n";

   

}

}
