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
我们遍历从 1 到 n 的每个整数,对于每个整数,我们检查它是否是 3 和 5 的倍数,或者只是 3 的倍数,或者只是 5 的倍数。根据检查的结果,我们将相应的字符串添加到答案数组中。
