Fizz Buzz - List - Easy - LeetCode

Fizz Buzz - List - Easy - LeetCode

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 IList<string> FizzBuzz(int n) {
        var res = new List<string>();
        for(int i=1;i<=n;i++){
            if(i%3==0 && i%5==0){
                res.Add("FizzBuzz");
            }
            else if(i%3==0){
                res.Add("Fizz");
            }
            else if(i%5==0){
                res.Add("Buzz");
            }
            else{
                res.Add(i.ToString());
            }            
        }
        
        return res;
    }
}
