Circular Linked List

Circular Linked List

A circular linked list is a linear data structure in which the last node points back to the first node, forming a loop. This structure allows for continuous traversal without any interruptions. Circular linked lists are particularly useful for tasks such as scheduling and managing playlists, as they enable smooth, cyclic navigation through the elements.

Unlike a regular linked list, which ends with a node pointing to NULL, the last node in a circular linked list points back to the first node. 

 

 

Circular linked lists are mostly used in task maintenance in operating systems. There are many examples where circular linked lists are being used in computer science including browser surfing where a record of pages visited in the past by the user, is maintained in the form of circular linked lists and can be accessed again by clicking the previous button.
