/***************************************************************************************
 *
 * 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"
 * ]
