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"
]

取余占cpu很多

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

不取余

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

    int fizz = 3;
    int buzz = 5;

    for(int i = 1; i <= n; i++){
        if(i == fizz && i == buzz){
            res.add("FizzBuzz");
            fizz += 3;
            buzz += 5;
        }

        else if(i == fizz){
            res.add("Fizz");

            fizz+=3;
        }
        else if(i == buzz){
            res.add("Buzz");
            buzz += 5;
        }
        else{
            res.add(String.valueOf(i));
        }
    }

    return res;
}

}
