Circular Linked List

What is Linked List?

A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. Linked list consists of nodes where each node contains a data field and a reference(link) to the next node in the list....

Singly Linked List:

A singly linked list is a linear data structure in which the elements are not stored in contiguous memory locations and each element is connected only to its next element using a pointer....

Doubly Linked List:

A doubly linked list (DLL) is a special type of linked list in which each node contains a pointer to the previous node as well as the next node of the linked list....

Circular Linked List:

The circular linked list is a linked list where all nodes are connected to form a circle. In a circular linked list, the first node and the last node are connected to each other which forms a circle. There is no NULL at the end....

Applications of Linked List:

Image viewer – Previous and next images are linked and can be accessed by the next and previous buttons.Previous and next page in a web browser – We can access the previous and next URL searched in a web browser by pressing the back and next buttons since they are linked as a linked list.Music Player – Songs in the music player are linked to the previous and next songs. So you can play songs either from starting or ending of the list.GPS navigation systems– Linked lists can be used to store and manage a list of locations and routes, allowing users to easily navigate to their desired destination....

Advantages of Linked Lists:

Dynamic Size: Linked lists can grow or shrink dynamically, as memory allocation is done at runtime.Insertion and Deletion: Adding or removing elements from a linked list is efficient, especially for large lists.Flexibility: Linked lists can be easily reorganized and modified without requiring a contiguous block of memory....

Disadvantages of Linked Lists:

Random Access: Unlike arrays, linked lists do not allow direct access to elements by index. Traversal is required to reach a specific node.Extra Memory: Linked lists require additional memory for storing the pointers, compared to arrays....
