Golang : Iterating Elements Over A List

In this short tutorial, we will learn how to iterate the elements over a list. The code below will populate the list first and then perform a "next" scan and then a "prev" scan to list out the elements inside the list.

 package main

 import (
 "container/list"
 "fmt"
 )

 func main() {
 alist := list.New()
 alist.PushBack("a")
 alist.PushBack("b")
 alist.PushBack("c")

 fmt.Println("Next")

 for e := alist.Front(); e != nil; e = e.Next() {
 fmt.Println(e.Value) // print out the elements
 }

 fmt.Println("---------")
 fmt.Println("Prev")

 for e := alist.Back(); e != nil; e = e.Prev() {
 fmt.Println(e.Value) // print out the elements
 }

 }

Output :

Next

a

b

c

---------

Prev

c

b

a
