/*Description:
Task:

Given a list of integers, determine whether the sum of its elements is odd or even.

Give your answer as a string matching "odd" or "even".

If the input array is empty consider it as: [0] (array with a zero).
Examples:

Input: [0]
Output: "even"

Input: [0, 1, 4]
Output: "odd"

Input: [0, -1, -5]
Output: "even"

Have fun!
