Queue Implementation Using a LinkedList

Explore how to implement a queue in Go using a linked list data structure. Learn to create the queue struct and perform key operations such as adding at the tail, removing from the head, peeking at the front element, and printing the queue contents. This lesson helps you understand how linked lists can efficiently support queue behaviors.

We'll cover the following...

We saw how to create a queue using an array data structure in the previous lesson. Nowe, let’s look at how we can implement a queue using a linked list data structure.

Queue struct

First of all, let’s define a struct for our queue.

Go (1.6.2)
type Node struct {
  value int
  next *Node
}
type QueueLinkedList struct {
  head *Node
  tail *Node
  size int
}
