  num = sc.nextInt();
  for (int r = 1, n = num; r <= num; r++, n–) 
  {
   for (int sp = r; sp > 1; sp–) {
    System.out.print(” “);
   }
   for (int c = r, p = n; c <= num; c++, p–) 
   {
    System.out.print(p);
   }
   for (int c = num – r, p = 2; c >= 1; c–, p++) 
   {
    System.out.print(p);
   }
