Thank you.In this assignment, you will use a modified Node structure to create a “Double Ended Doubly Linked List” data structure with extended functionality. The Node structure is defined as follows (we will use integers for data elements): public class Node { public int data; public Node next; public Node previous; } The Double Ended Doubly Linked List (DEDLL) class definition is as follows: public class DEDLL { public int currentSize; public Node head; public Node tail; } This design is a modification of the standard linked list. In the standard that we discussed in class, there is only a head node that represents the first node in the list and each node only contains a reference to the next node in the list until the chain of nodes reach null. In this DEDLL, each node also has a reference to the previous node. The…Course: Data Structure and Algorithims Language: Java Kindly make the program in 2 hours. Task is well explained.

The online rent a car system serves as a database storing available rental cars with their associated retailer. The system checks and shows a list of accessible rental cars to the user for a given time period. Then, they can book their desired car from the related store by using the program. The development language of the project is Java and 2 types of data structures are used: linked list and tree. All of the available option details of the cars are accumulated by linked lists and the customer information is stored in the tree.C++ Create a function called findData that will take the following parameter: “CHOICE, KEY”.
