#include <iostream>

using namespace std;

int main()

{

int n, A[51][51], i, j, nr=0;

cin>>n;

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

 if(i%2!=0)

  for(j=1;j<=n;j++){

   nr++; A[i][j]=nr;}

 else

  for(j=n;j>=1;j--){

   nr++; A[i][j]=nr;

  }

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

 for(j=1;j<=n;j++)

  cout<<A[i][j]<<' ';

 cout<<endl;

}

return 0;
