#include<stdio.h>
int main()
{

 int num,r,c,m,n,z,a;
 printf("Enter No. of Rows : ");
 scanf("%d", &num);
 z=num;
 n=1;
 for(r=1; r<=num; r++, n=n+7-r, z--)
 {
   m=n;
   a=num-r;
   for(c=1; c<=r; c++, m=m-a)
   {
      printf(" %d ", m);
      a++;
   }
   printf("\n");
 }
 getch();
 return 0;
}
