Circular linked list
CIRCULAR LINKED LIST CODE
Reverse of circular list is a complex as compared to singly or doubly lists.Circular lists are complex as compared to singly linked lists.The circular list never points to a NULL pointer unless fully deallocated. No requirement for a NULL assignment in the code.In a circular list, any node can be starting point means we can traverse each node from any point.Easily we can go to head from the last node.We can go to any node from any node in the Circular linked list which was not possible in the singly linked list if we reached the last node.Traversal of a circular linked list is the process of displaying the entire linked list’s contents and retracing back to the source node.The node can be identified by the occurrence of its value or by its position. Deletion is the process of removing an existing node from the linked list.Insertion is the process of placing a node at a specified position in the circular linked list.
The basic operations on a circular linked list are: Here a “node” is a self-referential element with pointers to one or two nodes in its immediate vicinity.īelow is a depiction of a circular linked list with 3 nodes.īasic Operations in Circular Linked lists A circular linked list is a sequence of nodes arranged in such a way that each node can be retraced to itself.
