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 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
解答
class Solution {
public List<String> fizzBuzz(int n) {
int threeTimes = 1, fiveTimes = 1;
List<String> result = new ArrayList<>();
for (int i = 1; i <= n; i++) {
if (i == 3*threeTimes) {
if (i == 5*fiveTimes) {
result.add("FizzBuzz");
fiveTimes++;
} else {
result.add("Fizz");
}
threeTimes++;
} else if (i == 5*fiveTimes) {
result.add("Buzz");
fiveTimes++;
} else {
result.add(""+i);
}
}
return result;
}
}
