Output - 1^3 + 5^3 + 3^3 = 153, so it is Armstrong no. */

class Armstrong {
 public static void main(String args[]) {
  int num = Integer.parseInt(args[0]);
  int n = num;                                   //use to check at last time
  int check = 0, remainder;
  while (num > 0) {
   remainder = num % 10;
   check = check + (int) Math.pow(remainder, 3);
   num = num / 10;
  }
  if (check == n)
   System.out.println(n + " is an Armstrong Number");
  else
   System.out.println(n + " is not a Armstrong Number");
 }
}
