In number theory there are many interesting numbers - eg. Armstrong numbers, Happy numbers, Meertens numbers, just to name a few.
In this bite, you will try to solve the Armstrong number question: given an integer, determine if it is an armstrong number.
An armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits. See this reference for more info and here are some examples:
a) 153 is an armstrong number. It's a 3 digits number:(1^3) + (5^3) + (3^3)= 153.
b) 371 is also an armstrong number.
c) any single digit numbers (1-9) are armstrong numbers as well.
