Ejemplo 4: problema de números armstrong java

import java.util.Scanner;

/*
 *@author: Mayank Manoj Raicha
 * Armstrong Number in Java: A positive number is called armstrong number if it is equal to the sum of cubes of its digits 
 * for example 0, 1, 153, 370, 371, 407 etc.
 * 153 = (1*1*1)+(5*5*5)+(3*3*3)  = 1+125+27 = 153
