📋Problem

Given an integer n, return a string arrayanswer (1-indexed) where:

answer[i] == "FizzBuzz" if i is divisible by 3 and 5.
answer[i] == "Fizz" if i is divisible by 3.
answer[i] == "Buzz" if i is divisible by 5.
answer[i] == i (as a string) if none of the above conditions are true.

Example 1:

**Input:** n = 3
**Output:** ["1","2","Fizz"]

Example 2:

**Input:** n = 5
**Output:** ["1","2","Fizz","4","Buzz"]

Example 3:

**Input:** n = 15
**Output:** ["1","2","Fizz","4","Buzz","Fizz","7","8","Fizz","Buzz","11","Fizz","13","14","FizzBuzz"]

Constraints:

1 <= n <= 104

💡Solution

java

class Solution {
    public List<String> fizzBuzz(int n) {
        List<String> res = new ArrayList<>();

        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;        
    }
}
