Description

Given an integer n, determine whether it is even.

An integer is even if it is divisible by 2 without leaving a remainder. Otherwise, it is odd. The number 0 is even, and negative integers are also valid inputs.

Return true when n is even and false when it is odd.

Examples:

n = 8 returns true.
n = 13 returns false.
n = -4 returns true.

Implement isEven(n).
