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.
