Fizz Buzz
难度简单224收藏分享切换为英文接收动态反馈
给你一个整数 n ,找出从 1 到 n 各个整数的 Fizz Buzz 表示,并用字符串数组 answer(下标从 1 开始)返回结果,其中:
- answer[i] == "FizzBuzz" 如果 i 同时是 3 和 5 的倍数。
- answer[i] == "Fizz" 如果 i 是 3 的倍数。
- answer[i] == "Buzz" 如果 i 是 5 的倍数。
- answer[i] == i (以字符串形式)如果上述条件全不满足。
示例 1:
输入: n = 3 输出: ["1","2","Fizz"]
示例 2:
输入: n = 5 输出: ["1","2","Fizz","4","Buzz"]
示例 3:
输入: n = 15 输出: ["1","2","Fizz","4","Buzz","Fizz","7","8","Fizz","Buzz","11","Fizz","13","14","FizzBuzz"]
提示:
- 1 <= n <= 104
我的代码:
class Solution { public: vector<string> fizzBuzz(int n) { vector<string> ans; for (int i = 1; i <= n; ++ i) { string t = ""; if (i % 3 == 0) t += "Fizz"; if (i % 5 == 0) t += "Buzz"; if (t.size() == 0) t += to_string(i); ans.push_back(t); } return ans; } };
