Hello everyone, I inserted a new node at the beginning of the linked list but i am not able to print it's data. It still says null Please guide me where i am doing wrong. Thank you! //initial head head = null //after inserting node - 30 at the beginnnig [30]-->null | head...
Java Data Structures - Circular linked lists Previous Quiz Next Circular Linked List is a variation of Linked list in which the first element points to the last element and the last element points to the first element. Both Singly Linked List and Doubly Linked List can be made into a ...

Linked List are linear data structures where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part. The elements are linked using pointers and addresses. Each element is known as a node. Due to the dynamicity and ease of...
The following methods we plan to implement as part of our stack implementation in Java using linked list. push(): Adds an item to the stack pop(): Return the top object from the stack, and remove as well.In addition to push() and pop() methods we can also define a few supporting ...

Thus, we can go in either direction: forward or backward. Doubly linked list A node is represented as struct node { int data; struct node *next; struct node *prev; } A three-member doubly linked list can be created as /* Initialize nodes */ struct node *head; struct node *one =...
