Queue Implementation Using Circular Linked List

Learn how to implement a queue by using a circular linked list.

We'll cover the following...

So far we’ve seen how to implement a queue using an array or a simple linked list. Now, let’s look at how we can implement a queue using a circular linked list.

Queue struct

First of all, let’s define a struct for our circular linked list.

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

Queue operations

Now, let’s make some common queue operations by ...
