This article mainly introduces the Go language list to get elements of the way there are related knowledge, content detailed and easy to understand, simple and fast operation, has a certain reference value, I believe that everyone read this Go language list to get elements of the way there are articles will be harvested, let's take a look at it.

Golang's list elements can be obtained by using the built-in Front function to obtain the head node, using the Back function to obtain the tail node, using Prev to obtain the previous node, and using Next to obtain the next node.

1. Obtain column header node

Front() *Element

package mainimport ( "container/list" "fmt")func main() { fmt.Println("www.haicoder.net") //Use the built-in Front() function to get the head node of the list listHaiCoder := list.New() listHaiCoder.PushFront("Hello") listHaiCoder.PushFront("HaiCoder") listHaiCoder.PushFront("Haike") element := listHaiCoder.Front() fmt.Println("Front =", element.Value)}

Use the built-in Front() function to get the head node of the list.

2. Get the list tail node

Back () *Element

package mainimport ( "container/list" "fmt")func main() { fmt.Println("www.haicoder.net") //Use the built-in Back() function to get the tail node of the list listHaiCoder := list.New() listHaiCoder.PushFront("Hello") listHaiCoder.PushFront("HaiCoder") listHaiCoder.PushFront("Haike") element := listHaiCoder.Back() fmt.Println("Back =", element.Value)}

Use the built-in Back() function to get the tail node of the list.

3. Get the previous node

Prev() *Element

package mainimport ( "container/list" "fmt")func main() { fmt.Println("www.haicoder.net") //Use the built-in Prev() function to get the previous node in the list listHaiCoder := list.New() listHaiCoder.PushFront("Hello") element := listHaiCoder.PushFront("HaiCoder") listHaiCoder.PushFront("Haike") preElement := element.Prev() fmt.Println("preElement =", preElement.Value)}

Use the built-in Prev() function to get the previous node in the list.

4. Get the next node

Next() *Element

package mainimport ( "container/list" "fmt")func main() { fmt.Println("www.haicoder.net") //Use the Next() function built into the list to get the next node in the list listHaiCoder := list.New() listHaiCoder.PushFront("Hello") element := listHaiCoder.PushFront("HaiCoder") listHaiCoder.PushFront("Haike") nextElement := element.Next() fmt.Println("nextElement =", nextElement.Value)}

Use the built-in Next() function to get the next node in the list.
