412 Fizz Buzz

Write a program that outputs a string representation of numbers from 1 to n.
1. If n is a multiple of 3, output "Fizz";
2. If n is a multiple of 5, output "Buzz";
3. If n is a multiple of 3 and 5, output "FizzBuzz".
Example:
n = 15,
returns:
[
    "1",
    "2",
    "Fizz",
    "4",
    "Buzz",
    "Fizz",
    "7",
    "8",
    "Fizz",
    "Buzz",
    " 11",
    "Fizz",
    "13",
    "14",
    "FizzBuzz"
]
