412. Fizz Buzz

題意：將3和5的公倍數返回“FizzBuzz”，只是3的公倍數返回“Fizz”，只是5的公倍數返回“Buzz”，否則返回字符型數值

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));//轉換成字符串
    }
    return res;
    }
};
