Insert and Delete at Head and Tail of Linked List in …

WebLinked lists are linear data structures that hold data in individual objects called nodes. These nodes hold both the data and a reference to the next node in the list. Linked lists are often used because of their efficient insertion and deletion. They can be used to implement stacks, queues, and other abstract data types. You can visualize a linked list … WebMar 9, 2024 · Insert an Element at the End of the Circular Doubly Linked List. Create a node temp with the given data. If the list is empty, create a node temp with given data and point temp->prev and temp->next to itself and set it as head and return. Perform the steps used to insert at the beginning, excluding the last step.
