   {
     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");
