Armstrong.java

//An Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits.
//For instance, a 3 digit number will be considered an Armstrong number if the sum of the cubes of its digits is equal to the number itself. 
//For example, 153 is an Armstrong number, as 1*3 + 53 + 3*3 = 153
