Write A Program To Find Armstrong Number Where Entered Number Of Digits Is The Power Of Each Digits Of The Number And There Sum Is Equal To The Number Itself?

An Armstrong number is an n-digit number that is equal to the sum of the n^thpowers of its digits. In this lesson, students will explore Armstrong
numbers, identify all Armstrong numbers less than 1000, and investigate
a recursive sequence that uses a similar process. Throughout the
lesson, students will use spreadsheets or other technology.illuminations
The  program computes all Armstrong numbers in the range of! 0 and 999.
