1. A polynomial can be represented as a linked list, where each node called a polyNode contains the coefficient and the exponent of a term of the polynomial. For example, the polynomial 4x³ + 3x² - 5 would be represented as the linked list: 43 4x3 → 32- > 50/ 3x2 Write a Polynomial class that has methods for creating a polynomial, reading and writing a polynomial, and adding a pair of polymomials. In order to add 2 polynomials, traverse both lists. If a particular exponent value is present in either one, it should also be present in the resulting polynomial unless its coefficient is zero.

- Implement a Single linked list to store a set of Integer numbers (no duplicate) Using Java lanaguage• Instance variable• Constructor• Accessor and Update methods 3. Define TestSLinkedList Classa. Declare an instance of the Single List class.b. Test all the methods of the Single List class.c)Define a class that implementsa singly linked list with the following methods, assuming that the first node of a linked list is referred to by head:i) A constructor.ii) searchNode that takes asparameter an integer value and returns a reference to the node with that value if it is found,and null otherwise. i)addlnOrder that allows insertion of a node to the linked list such that the list remainssorted in ascendingorder.iv) displayList which displays all the nodes in the linked list.d) Assuming that the class defined in part (c) aboveis used to implement a queueofpositive integers, define the following methods which can be used to implement queueoperations:i) isEmptythat returns true if the queue is empty andfalse otherwise.ii) pop that returns the value of the first node if the linked list is not empty,and -1 otherwise.iii) push that takes as parameteran integer value and adds it to the end of the queue.Write a Java class myLinkedList to simulate a singly linked list using arrays as the underlying structure. Include the following methods: 1. insert an element within the linked list.(this should also work for the front and the rear of the list) 2. Remove an element from the linked list 3. Display (print) the elements of the linked list in order. 4. A method to check if the list is "empty". Test your solution using a linked list that initially has the characters A, B, D, E, F, and G. Insert "C" between B and D. Remove element "F". [Hint: One solution (recommended) is to use 2 arrays. One for the data, and the other for the "next" pointer. Also, consider using dummy nodes for the front, and possibly the rear of the list] Extend the solution so that it simulates a doubly linked list! (hint: You will need a third array to represent the "backward" pointers)
- Can anyone please solve this question asap ? Thank yoyuIn this question, you are required to implement singly linked list and its concepts to solve the problems of a departmental store described in the scenario given below:A departmental store has a variety of products to sell. Each product type has a unique ID and price associated with it (for example soaps can have an ID of 1 and price of 50 etc.). A customer comes to the store and starts putting items in his/her shopping cart. Once all theitems have been placed in the shopping cart, the customer then proceeds to checkout but before that, he/she will sort (in ascending order of IDs) the shopping cart’s items and proceed to remove all the duplicate items from the shopping cart, that is if two soaps have been added to the cart, only 1 will be kept. At the checkout counter, he/she will then remove items from the cart by removing from the end of the shopping cart (linked list). A bill for that customer is then generated and printed.You…Please do not copy from chegg. C++ Dividing a linked list into two sublists of almost equal sizes Add the operation divideMid to the class ListData in Chapter17.cpp on Canvas as follows: void divideMid(ListData &sublist); //This operation divides the given list into two sublists //of (almost) equal sizes. //Postcondition: first points to the first node and last // points to the last node of the first sublist. // sublist.first points to the first node // and sublist.last points to the last node // of the second sublist. Consider the following statements: ListData myList; ListData subList; Suppose myList points to the list with elements 34 65 27 89 12 (in this order). The statement: myList.divideMid(subList); divides myList into two sublists: myList points to the list with the elements 34 65 27, and subList points to the sublist with the elements 89 12. Write the definition of the function template to implement the operation divideMid. chapter 17.cpp #include…Implement a simple linked list in Python (Write source code and show output) with basic linked list operations like: (a) create a sequence of nodes and construct a linear linked list. (b) insert a new node in the linked list. (b) delete a particular node in the linked list. (c) modify the linear linked list into a circular linked list. Use this template: class Node:def __init__(self, val=None):self.val = valself.next = Noneclass LinkedList:"""TODO: Remove the "pass" statements and implement each methodAdd any methods if necessaryDON'T use a builtin list to keep all your nodes."""def __init__(self):self.head = None # The head of your list, don't change its name.

- Please code this question in Java according to the function attached in picture. Given two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1's digit is at the head of the list. Write a function that adds the two numbers and return the sum as linked list: Example : Input : (7-> 1 -> 6) + (5-> 9-> 2). That is 617 + 295 = 912 Output : 2-> 1 -> 9 Expected time complexity : O(m+n), where m and n are no. of nodes in first and second linked list respectively.(Implement a doubly linked list) The MyLinkedList class used in Listing 24.6 is a one-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new data field name previous to refer to the previous node in the list, as follows:public class Node<E> { E element; Node<E> next; Node<E> previous;public Node(E e) { element = e; } }Implement a new class named TwoWayLinkedList that uses a doubly linked list to store elements. The MyLinkedList class in the text extends MyAbstractList. Define TwoWayLinkedList to extend the java.util.AbstractSequentialList class. You need to implement all the methods defined in MyLinkedList as well as the methods listIterator() and listIterator(int index). Both return an instance of java.util. ListIterator<E>. The former sets the cursor to the head of the list and the latter to the element at the specified index.In Java. The following is a class definition of a linked list Node:class Node{int info;Node next;}Show the instructions required to create a linked list that is referenced by head and stores in order, the int values 13, 6 and 2. Assume that Node's constructor receives no parameters.
