# Instructions Write a function to determine if a number _n_ 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. 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. # Examples
isArmstrongNumber 10

isArmstrongNumber 153

# Objectives - Implement the `isArmstrongNumber` function in APL. - Run the test suite and make sure that it succeeds. - Submit your solution and check it at the website.
