412. Fizz Buzz

Easy

Given an integer n, return a string array answer (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

解題

func fizzBuzz(n int) []string {
    var ans []string
    
    for i:=1; i<=n; i++ {
        t := i%3
        f := i%5
        if t==0 && f==0 {
            ans = append(ans, "FizzBuzz")
        } else if t==0 {
            ans = append(ans, "Fizz")
        } else if f==0 {
            ans = append(ans, "Buzz")
        } else {
            ans = append(ans, strconv.Itoa(i))
        }
    }
    
    return ans
}
