fizzbuzz

請實作一個 method, 參數為 n，回傳一個 array

```
func getFizzBuzz(n int) []string {
		// TODO
}
```

1. n 代表的是要回傳的陣列數字 1 ~ n, e.g. n = 6, 代表的是要計算 1 ~ 3，回傳 answer = ["1", "2", "Fizz"]
2. 承上會從 1 到 n 去計算
	a. 如果 i 可以被 3 整除，則回傳 ["Fizz"]
	b. 如果 i 可以被 5 整除，則回傳 ["Buzz"]
	c. 如果 i 可以被 3&5 整除，則回傳 FizzBuzz
	d. 如果都沒有，則回傳 原本的數字 i

範例：
getFizzBuzz(3) = ["1", "2", "Fizz"]
getFizzBuzz(5) = ["1","2","Fizz","4","Buzz"]
getFizzBuss(15) = ["1","2","Fizz","4","Buzz","Fizz","7","8","Fizz","Buzz","11","Fizz","13","14","FizzBuzz"]
