题解：

func fizzBuzz(n int) (ans []string) {
    for i := 1; i <= n; i++ {
        sb := &strings.Builder{}
        if i%3 == 0 {
            sb.WriteString("Fizz")
        }
        if i%5 == 0 {
            sb.WriteString("Buzz")
        }
        if sb.Len() == 0 {
            sb.WriteString(strconv.Itoa(i))
        }
        ans = append(ans, sb.String())
    }
    return
}
