LeetCode(Math)Fizz Buzz

Fizz Buzz

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"
]

思路：看懂题意以后就很简单了，仔细考虑清楚怎么判断更合理即可。

java代码如下：

class Solution {
    public List<String> fizzBuzz(int n) {
        List<String> res=new ArrayList<String>();
        if(n==0){
            return res;
        }
        for(int i=1;i<=n;i++){
            if(i%3==0){
                if(i%5==0){
                    res.add("FizzBuzz");
                    continue;
                }else{
                    res.add("Fizz");
                    continue;
                }
            }
            if(i%5==0){
                res.add("Buzz");
                continue;
            }
            res.add(String.valueOf(i));
        }
        return res;
    }
}
