Go slice 底层数组题

请写出下面代码的输出结果

⭐⭐⭐⭐

func main() {
	type Map map[string][]int
	m := make(Map)
	s := []int{1, 2}
	s = append(s, 3)
	fmt.Printf("%+v\n", s)
	m["q1mi"] = s
	s = append(s[:1], s[2:]...)
	fmt.Printf("%+v\n", s)
	fmt.Printf("%+v\n", m["q1mi"])
}

问题简化为

	s := []int{1, 2, 3}
	s2 := s
	fmt.Println(s, s2)

	s = append(s[:1], s[2:]...)
	fmt.Println(s, s2)
