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 = 9^1 = 9
10 != 1^2 + 0^2 = 1
153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153
154 != 1^3 + 5^3 + 4^3 = 1 + 125 + 64 = 190
Write some code to determine whether a number is an Armstrong number.
