What is a linked list?

A linked list is a set of dynamically allocated nodes, arranged in such a way that each node contains one value and one pointer. The pointer always points to the next member of the list. If the pointer is nullptr, then it is the last node in the list.

What is a circular linked list?

3. Circular linked list: In a circular linked list, the last node points back to the head node, creating a circular structure. It can be either singly or doubly linked. Insertion: Adding a new node to a linked list involves adjusting the pointers of the existing nodes to maintain the proper sequence.

What is the difference between linked list and data structure?

Linked List is a linear data structure, in which elements are not stored at a contiguous location, rather they are linked using pointers. Linked List forms a series of connected nodes, where each node stores the data and the address of the next node. Data: It holds the actual value or data associated with the node.

What is a pointer in a linked list?

The pointer always points to the next member of the list. If the pointer is nullptr, then it is the last node in the list. A linked list is held using a pointer which points to the first item of the linked list called "head" and a pointer which points to the last item of the linked list called "tail".
