* 412. Fizz Buzz
* 给你一个整数 n ,找出从 1 到 n 各个整数的 Fizz Buzz 表示,并用字符串数组 answer(下标从 1 开始)返回结果,其中:
* answer[i] == "FizzBuzz" 如果 i 同时是 3 和 5 的倍数。
* answer[i] == "Fizz" 如果 i 是 3 的倍数。
* answer[i] == "Buzz" 如果 i 是 5 的倍数。
* answer[i] == i (以字符串形式)如果上述条件全不满足。
*
* 输入:n = 3
* 输出:["1","2","Fizz"]
*
* 输入:n = 5
* 输出:["1","2","Fizz","4","Buzz"]
*
* 输入:n = 15
* 输出:["1","2","Fizz","4","Buzz","Fizz","7","8","Fizz","Buzz","11","Fizz","13","14","FizzBuzz"]
