package javaapplication1;

// An Armstrong number of three digits is an integer that the sum 
// of the cubes of its digits is equal to the number itself

// 371 is an Armstrong number: 3**3 + 7**3 + 1**3 = 371

public class JavaApplication1 {
 
    public static void main(String[] args) {
        
        int n = 371, reminder, sum = 0, tmp;

        tmp = n;

        while (n != 0)
        {
            reminder = n % 10;
            n = n / 10;
            sum = sum + (reminder * reminder * reminder);
        }
        
        if (sum == tmp)
            System.out.format("%d is an Armstrong number\n", tmp);
        else
            System.out.format("%d is not an Armstrong number\n", tmp);
    }
}
   
/*
run:
  
371 is an Armstrong number
   
*/
