# Armstrong Numbers
Welcome to Armstrong Numbers on Exercism's Emacs Lisp Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
An [Armstrong number](https://en.wikipedia.org/wiki/Narcissistic_number) is a number that is the sum of its own digits each raised to the power of the number of digits.
For example:
- 9 is an Armstrong number, because `9 = 9^1 = 9`
- 10 is *not* an Armstrong number, because `10 != 1^2 + 0^2 = 1`
- 153 is an Armstrong number, because: `153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153`
- 154 is *not* an Armstrong number, because: `154 != 1^3 + 5^3 + 4^3 = 1 + 125 + 64 = 190`
Write some code to determine whether a number is an Armstrong number.
