golang的list数据结构demo

package main
import "container/list"
func main(){        
　　　var mylist list.List

    //放在尾部
    mylist.PushBack("go")
    mylist.PushBack("grpc")
    mylist.PushBack("mysql")

    //头部放数据
    mylist.PushFront("gin")

    //在grpc前插入元素java
    i := mylist.Front()
    for ; i != nil; i = i.Next() {
        if i.Value.(string) == "grpc" {
            break
        }
    }
    mylist.InsertBefore("java", i)

    //删除grpc元素
    i := mylist.Front()
    for ; i != nil; i = i.Next() {
        if i.Value.(string) == "grpc" {
            break
        }
    }
    mylist.Remove(i)

    //遍历打印值,正序
    for i := mylist.Front(); i != nil; i = i.Next() {
        fmt.Println(i.Value)
    }

    //反向遍历
    for i := mylist.Back(); i != nil; i = i.Prev() {
        fmt.Println(i.Value)
    }
}
