[Leetcode] 412. Fizz Buzz 解题报告

题目：

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"
]

思路：

练手题目^_^。

代码：

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