Advertisements List<String> list = new LinkedList(); This "list" is created in java. As we know , every class in Collections framework has some underlying data structure. LinkedList in java has Linear LinkedList implementation or Doubly LinkedList implementation as its underlying Data structure? >Solution : According to the documentation LinkedList is an implementation of the Doubly-linked… Read More Underlying data structure of LinkedList Class implementing collections interface in java is Linear or Doubly?

Advertisements So I have created two structures LIST (consists of head and last pointer) and NODE (consists of next and previous pointer). I have a function create_list(LIST *p) that does the following: i) Sets the head and last pointer to NULL ii) Asks the user to enter the no of nodes for the list and… Read More Not able to create a second doubly linked list

Advertisements I’m curious as to what is the correct way of deleting all nodes in a doubly linked list. Here’s my linked list structure: type ListNode struct { Data branch Next *ListNode Prev *ListNode } type doublyLinkedList struct { Head *ListNode Tail *ListNode Size int } Will it work if I just point the Head… Read More How to delete all nodes in doubly linked list?

Advertisements I want to create a C program to create a doubly linked list of character arrays. The input would be given like in a menu, with particular conditions for adding an element, breaking away etc. Initially I am only accepting the character input ‘V’ to create the list, otherwise the program breaks off. But… Read More If else loop working in an unexplainable manner

Advertisements So I revisited double linked list, found I’m really stupid, and can’t figure things out even when I narrowed down problem to delete operator. I’m still playing around with templates, so maybe there’s something wrong with templates as well. Print works fine without deleting a node. Please tell me what’s wrong. Result of code… Read More Delete in Linked List

Advertisements I am new to java algorithms and doubly linked list. I have been playing around with them quite a lot trying to learn. What would be the best way to make this algorithm run in O(1) instead of O(n) (its a doubly linked list)? I appreciate any help. public void add(E e) { Node<E>… Read More Is there a way I can make this easily run in constant time instead of linear time?
