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"]

被3和5整除的话是FizzBuzz，只被3整除的话是Fizz，只被5整除的话是Buzz，其于情况是自身。

代码：

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