What is the usage of list in go language?

Usage of list in go language: 1. Declare the linked list through "l := list.New()"; 2. Use "list.Remove(element)" to delete elements; 3. Use "list1 .PushBackList(list2)" method to merge the two linked lists.

import (
        "container/list"
        "fmt"
)

Traversing the list of

go is also implemented using a two-way circular linked list, and PushBack() is used to append at the end

// 声明链表
l := list.New()
// 数据添加到尾部
l.PushBack(4)
l.PushBack(5)
l.PushBack(6)
// 遍历
for e := l.Front(); e != nil; e = e.Next() {
     fmt.Printf("%v\n", e.Value)
}

Delete elements

Delete using list.Remove(element)

 l := list.New()
 l.PushBack(4)
 six := l.PushBack(6)
 l.Remove(six) // 删除6这个节点

Merge two linked lists (list1)

Use list1.PushBackList(list2)

l := list.New()
l.PushBack(1)
l.PushBack(2)
l.PushBack(3)
l2 := list.New()
l2.PushBack(4)
l2.PushBack(5)
l2.PushBack(6)
l2.PushBackList(l2)
fmt.Printf("merge after l================\n")
for e := l.Front(); e != nil; e = e.Next() {
        fmt.Printf("%d\n", e.Value.(int))
}
fmt.Printf("merge after l2================\n")
for e := l2.Front(); e != nil; e = e.Next() {
        fmt.Printf("%d\n", e.Value.(int))
}
