Fizz Buzz 问题
给你一个整数n. 从 1 到 n 按照下面的规则打印每个数:
- 如果这个数被3整除,打印fizz.
- 如果这个数被5整除,打印buzz.
- 如果这个数能同时被3和5整除,打印fizz buzz.
样例
比如 n = 15, 返回一个字符串数组:
[
"1", "2", "fizz",
"4", "buzz", "fizz",
"7", "8", "fizz",
"buzz", "11", "fizz",
"13", "14", "fizz buzz"

枚举法 基本实现
code
class Solution {
public:
/**
* param n: As description.
* return: A list of strings.
*/
vector<string> fizzBuzz(int n) {
vector<string> result;
for (int i = 1; i <= n; i++) {
if (i % 15 == 0) {
result.push_back("fizz buzz");
} else if (i % 3 == 0) {
result.push_back("fizz");
} else if (i % 5 == 0) {
result.push_back("buzz");
} else {
result.push_back(to_string(i));
}
}
return result;
}
};
