412. Fizz Buzz

题意：将3和5的公倍数返回“FizzBuzz”，只是3的公倍数返回“Fizz”，只是5的公倍数返回“Buzz”，否则返回字符型数值

class Solution {public:    vector<string> fizzBuzz(int n) {    vector<string>res;    if(n==0)return res;    for(int i=1;i<=n;i++)    {        if(i%3==0&&i%5==0)            res.push_back("FizzBuzz");        else if(i%3==0)            res.push_back("Fizz");        else if(i%5==0)            res.push_back("Buzz");        else            res.push_back(to_string(i));//转换成字符串    }    return res;    }};
