Armstrong Numbers
Welcome to Armstrong Numbers on Exercism's Elixir Track.
If you need help running the tests or submitting your code, check out HELP.md
.
Instructions
An Armstrong 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.
