Doubly Linked List (DLL) is a complex data structure and an advanced version of a simple linked list in which the node has a pointer to the next node only. As we can traverse the elements in only one direction, reverse traversing is not possible. To solve this problem, a doubly-linked ...
A doubly linked list plays a pivotal role in C++, which is used for many of the operations and manipulations with elements present within the entire list. A doubly linked list is made up of many nodes represented back to back, which is created and uses self-referencing pointers. Nodes prese...
3. Doubly linked list in Java The doubly linked list, as its name implies, includes two pointers. The doubly linked list may be described as a three-part linear data structure: the data component, the address part, and the other two address parts. Adoubly linked list,in other terms, is...
Syntax to create a table in ORACLE DB: CREATE TABLE EMPLOYEE ( ID int NOT NULL PRIMARY KEY, LastName varchar(255), FirstName varchar(255) ); Java Program: package com.STH.JDBC; import java.sql.BatchUpdateException; import java.sql.Connection; ...
Transitioning to more complex data structures, let's explore the Stack and Queue.A Stack is a linear data structure that adheres to a specific order for its operations. This order can be LIFO (Last In First Out) or FILO (First In Last Out)....

Use doubly Linked list with hashmap of pointers to linked list nodes. add unique number to the linked list. When add is called check if the added number is unique then it have to be added to the linked list and if it is repeated remove it from the linked list if exists. When showFi...
All leaf pages of an index contain pointers to the next and the previous pages in the index. This forms a doubly linked list of all index/data pages. Ideally, the physical order of the pages in the data file should match the logical ordering. When mismatch happens fragmentation occurs....
Deque is adouble-ended queuein whichwe can add/delete elements from both ends. A Deque can be implemented using adoubly-linked list/ linked listin Java. Deque can be used in scenarios like designing a ticket counter (detailed explanation done in the previous article). ...
