Circular Linked List | Advantages | Traversing | BitsOfCS

Circular Linked list is a sequence of nodes in which every node connects to its next node in the sequence, by the pointer. The last node also connects to the first node in the sequence.

Hence a circular linked list is similar to the singly linked list with an extra pointer. The last node instead of having a NULL pointer, has the address of the first node.

Example– Below circular linked list having four nodes and the last node has the address of the first node.

Advantages of Circular Linked List:

1. No node in the circular linked list doesn’t have the NULL pointer.

2. In a circular linked list, any node can be a starting node. Because we can traverse all nodes by starting from any node and we just need to stop when the first visited node is visited again.

3. Circular linked list is also useful for implementation of queue data structure. Because, when we implement a queue using a singly linked list we have to maintain two pointers (front and rear). But when we implement a queue using a circular linked list, we have to maintain a single pointer to the last inserted node and the front node can always be obtained as next to the last node.

Output–

This is how our circular linked list looked like:
