题目描述:
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"]
思路:
- 初始化i = 1(1 <= i <= n)
- 遍历i
- i模15, i模3,i模5.取模结果等于0,则记录对应结果,否则则记录i.
代码实现:
class Solution {
public List<String> result = new ArrayList();
public List<String> fizzBuzz(int n) {
String a = "Fizz";
String b = "Buzz";
String c = "FizzBuzz";
for (int i = 1; i <= n; i++) {
if (i % 3 == 0 && i % 5 == 0) {
result.add(c);
} else if (i % 3 == 0) {
result.add(a);
} else if (i % 5 == 0) {
result.add(b);
} else {
result.add(String.valueOf(i));
}
}
return result;
}
}
