/**
 * Created by peboov on 2017/6/20.
 *
 * Write a program that outputs the string representation of numbers from 1 to n.
 *
 * But for multiples of three it should output “Fizz” instead of the number
 * and for the multiples of five output “Buzz”.
 * For numbers which are multiples of both three and five output “FizzBuzz”.
 *
 * Example:
 *
 * n = 15,
 *
 * Return:
 * [
 * "1",
 * "2",
 * "Fizz",
 * "4",
 * "Buzz",
 * "Fizz",
 * "7",
 * "8",
 * "Fizz",
 * "Buzz",
 * "11",
 * "Fizz",
 * "13",
 * "14",
 * "FizzBuzz"
 * ]
