### 题目描述
2+
3+
这是 LeetCode 上的 **[412. Fizz Buzz](https://leetcode-cn.com/problems/fizz-buzz/solution/gong-shui-san-xie-jian-dan-mo-ni-ti-by-a-jll0/)** ,难度为 **简单**。
4+
5+
Tag : 「模拟」
6+
7+
写一个程序,输出从 `1` 到 `n` 数字的字符串表示。
8+
9+
1. 如果 `n` 是 `3` 的倍数,输出 `"Fizz"`;
10+
11+
2. 如果 `n` 是 `5` 的倍数,输出 `"Buzz"`;
12+
13+
3. 如果 `n` 同时是 `3` 和 `5` 的倍数,输出 `"FizzBuzz"`。
14+
15+
示例:
16+
```
17+
n = 15,
18+
19+
返回:
20+
[
21+
"1",
22+
"2",
23+
"Fizz",
24+
"4",
25+
"Buzz",
26+
"Fizz",
27+
"7",
28+
"8",
29+
"Fizz",
30+
"Buzz",
31+
"11",
32+
"Fizz",
33+
"13",
34+
"14",
35+
"FizzBuzz"
36+
]
37+
```
38+

41+
### 模拟
42+
43+
根据题意进行模拟。
44+
45+
代码:
46+
```Java []
47+
class Solution {
48+
public List<String> fizzBuzz(int n) {
49+
List<String> ans = new ArrayList<>();
50+
for (int i = 1; i <= n; i++) {
51+
String cur = "";
52+
if (i % 3 == 0) cur += "Fizz";
53+
if (i % 5 == 0) cur += "Buzz";
54+
if (cur.length() == 0) cur = i + "";
55+
ans.add(cur);
56+
}
57+
return ans;
58+
}
59+
}
60+
```
61+
* 时间复杂度:$O(n)$
62+
* 空间复杂度:$O(n)$

### 最后
67+
68+
这是我们「刷穿 LeetCode」系列文章的第 `No.412` 篇,系列开始于 2021年01月01日,截止于起始日 LeetCode 上共有 1916 道题目,部分是有锁题,我们将先把所有不带锁的题目刷完。
69+
70+
在这个系列文章里面,除了讲解解题思路以外,还会尽可能给出最为简洁的代码。如果涉及通解还会相应的代码模板。
71+
72+
为了方便各位同学能够电脑上进行调试和提交代码,我建立了相关的仓库:https://github.com/SharingSource/LogicStack-LeetCode 。
73+
74+
在仓库地址里,你可以看到系列文章的题解链接、系列文章的相应代码、LeetCode 原题链接和其他优选题解。
