In CIRCULAR LINKED LIST all the nodes in the linked list are connected circularly. The first and the last node are connected, the NULL is not present in the Circular linked list as the LAST NODE will be connected with the FIRST NODE.
A circular linked list is of TWO TYPES:
1) Circular single linked list: A Mix of a Circular linked list and a single link list, it has circular properties integrated with a single linked list.
In a circular singly linked list, the last node is connected to the first node, thus creating a loop. Traversing the list involves moving through the nodes until returning to the starting point. This type of list has no distinct beginning or end. Unidirectional in nature.
2) Circular Doubly linked list: A Mix of Circular linked list and double link list, it has circular properties integrated with a double linked list.
A circular doubly linked list combines the properties of both a doubly linked list and a circular linked list. In this type of list, two consecutive nodes are connected by the previous and next pointers. Bi-directional in nature.
NOTE: You can start traversing the entire list from any node, allowing flexibility in choosing a starting point. This method is advantageous for queue implementation, as it eliminates the need to store pointers for both the front and rear. By maintaining a pointer to the last inserted node, the next node after the last can always be obtained as the front. Linked list operations can become complex if not well documented.
