412. Fizz Buzz

Write a program that outputs the string representation of numbers from 1 to n.

But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Example:

n = 15,

Return:
[
    "1",
    "2",
    "Fizz",
    "4",
    "Buzz",
    "Fizz",
    "7",
    "8",
    "Fizz",
    "Buzz",
    "11",
    "Fizz",
    "13",
    "14",
    "FizzBuzz"
]

不知道这题有什么意义

class Solution {
public:
    vector<string> fizzBuzz(int n) {
        vector<string> v;
        for (int i = 1; i <= n ; ++i) {
            if (i % 15 == 0) {
                v.push_back("FizzBuzz");
            }
            else if (i % 3 == 0) {
                v.push_back("Fizz");
            }
            else if (i % 5 == 0) {
                v.push_back("Buzz");
            }
            else {
                v.push_back(to_string(i));
            }
        }
        return v;
    }
};
