[LeetCode] 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"
]

根据题意，根据条件的不同，产生的结果也不同，故使用if..else if...语句进行选择判断。

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