Fizz Buzz
作者:互联网
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
代码:
1 class Solution { 2 public: 3 vector<string> fizzBuzz(int n) 4 { 5 vector<string> answer; 6 for(int i=1;i<=n;i++) 7 { 8 if(i%3==0&&i%5!=0) 9 { 10 answer.push_back("Fizz"); 11 } 12 else if(i%3!=0&&i%5==0) 13 { 14 answer.push_back("Buzz"); 15 } 16 else if(i%3==0&&i%5==0) 17 { 18 answer.push_back("FizzBuzz"); 19 } 20 else 21 { 22 answer.push_back(to_string(i)); 23 } 24 } 25 return answer; 26 } 27 };
最初没有用vector一直编错,后来学习了一下使用后还是报错,才发现if条件里面用的不是i而是n,这样再想的话,最初用n并且没有用vector的话可能可以做出来。
