412. Fizz Buzz

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

比较简单，遍历判断push对应字符串就行

代码

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