LeetCode 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" ]

題目

給你一個整數n. 從 1 到 n 按照下面的規則打印每一個數：

• 若是這個數被3整除，打印fizz.
• 若是這個數被5整除，打印buzz.
• 若是這個數能同時被3和5整除，打印fizz buzz.

代碼

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