What are the Armstrong numbers?

What are the Armstrong numbers?

A Armstrong number of three digits is an integer, so the sum of the cubes of its digits is equal number itself. For example, 371 is a Armstrong number since 3 ** 3 + 7 ** 3 + 1 ** 3 = 371. Write a program to find them all Armstrong number in the range from 0 to 999.
