# Interview Solution

For a long time it puzzled me how something so expensive, so leading edge, could be so useless. And then it occurred to me that a computer is a stupid machine with the ability to do incredibly smart things, while computer programmers are smart people with the ability to do incredibly stupid things. They are, in short, a perfect match. Bill Bryson

### Interview Problem

An Armstrong Number is a number that is the sum of its own digits each raised to the power of the number of digits
Armstrong numbers are those numbers in which sum of cube of all digits provides the same number.
Example:-
153
1^3 = 1
5^3 = 125
3^3 = 27
1^3 + 5^3 + 3^3
= 1 + 125 + 27
= 153

### Output

```
153 is an Armstrong Number!
12 is not an Armstrong Number!

```
