Leetcode刷题（4）

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

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

Example:

n = 15,

Return:

[

    "1",

    "2",

    "Fizz",

    "4",

    "Buzz",

    "Fizz",

    "7",

    "8",

    "Fizz",

classSolution {

public:

    vector<string> fizzBuzz(int n) {

        vector<string> find(n);

        string str;

        for(int i=1; i<=n; i++) {

            if(i % 3 == 0) {

                if(i % 5 == 0) {

                    find[i-1] ="FizzBuzz";

                }

                else find[i-1] = "Fizz";

            }

            else if(i % 5 ==0)

             find[i-1] = "Buzz";

            else{

                str = to_string(i);

                find[i-1] = str;

            }

        }

        return find;

    }
