大佬，猜一下结果是什么

func main() {
s := make([]int, 0)
//s = []int{0, 10, 100}
s = append(s, 0)
s = append(s, 10)
s = append(s, 100)
fmt.Printf("main 内存地址：%p\n", s)
hello(s)
fmt.Println(s[0:len(s)])
fmt.Println(cap(s))
fmt.Println(s[0:cap(s)])
}

func hello(s []int) {
fmt.Printf("hello 内存地址：%p\n", s)
s = append(s, 1000)
s = append(s, 10000)
s = append(s, 100000)
s = append(s, 1000000)
s = append(s, 10000000)
s[0] = 1000
}
