1. 问题描述

Write a program that outputs the string representation of numbers from 1 to n.

But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Example:

n = 15,

Return: [ "1", "2", "Fizz", "4", "Buzz", "Fizz", "7", "8", "Fizz", "Buzz", "11", "Fizz", "13", "14", "FizzBuzz" ]

2. 解题思路

  • 根据 3, 5, 15 的倍数进行不同的处理
  • 注意把15 的 倍数的判断放在第一个

3. 代码

代码语言:javascript复制
class Solution {
   public List<String> fizzBuzz(int n) {
       List<String> result = new ArrayList<>();
       
       for(int i = 1; i <= n; i  ) {
           
           if (i % 15 == 0){
               result.add("FizzBuzz");
           } else if (i % 5 == 0) {
               result.add("Buzz");
           } else if (i % 3 == 0) {
               result.add("Fizz");
           } else{
               result.add(String.valueOf(i));
           }
       }
       
       return result;
       
   }
}
