LeetCode: 412. Fizz Buzz

LeetCode: 412. 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” ]

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

速度最快的：

public class Solution {    public List<String> fizzBuzz(int n) {        String[] result = new String[n];        for(int i=1;i<=n;i++) {            if(i%3==0 && i%5==0) {                result[i-1] = "FizzBuzz";            } else if(i%3==0) {                result[i-1] = "Fizz";            } else if(i%5==0) {                result[i-1] = "Buzz";            } else {                result[i-1] = String.valueOf(i);            }        }        return Arrays.asList(result);    }}
