"""
An Armstrong number is equal to the sum of the cubes of its digits.
An Armstrong number is equal to the sum of its own digits each raised
to the power of the number of digits.
For example, 370 is an Armstrong number because 3*3*3 + 7*7*7 + 0*0*0 = 370.
An Armstrong number is often called Narcissistic number.
