Golang : Linked list example

In Golang, I would say that slices superseded list.... as slices would allow you to dynamically resize, pop, push, cut, delete and copy. However, if you still want to use list for LIFO-FIFO stuff... you can use the container/list package.

Here is a linked list example in Golang.

 package main

 import (
  "container/list"
  "fmt"
 )

 func main() {
  // create a new link list
  alist := list.New()

  fmt.Println("Size before : ", alist.Len()) // list size before

  // push element into list
  alist.PushBack("a")
  alist.PushBack("b")
  alist.PushBack("c")

  fmt.Println("Size after insert(push): ", alist.Len()) // list size after

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

  // pop 3 elements
  alist.Remove(alist.Front())
  alist.Remove(alist.Front())
  alist.Remove(alist.Front())

  fmt.Println("Size after remove(pop) : ", alist.Len()) // list size after

 }

Output :

Size before : 0

Size after insert(push): 3

a

b

c

Size after remove(pop) : 0
