- In a doubly linked list of five nodes, if n points at the first node and p points at the second node, which of the following expressions does not refer to the third node in the list? a. p.next b. n.next.next.prev.next c. p.prev.next d. p.next.prev.next e. n.next.nextExercise 2 Given the following function to update a node in a standard linked list:public boolean update(Node head, int oldValue, int newValue){if (head == null)return false;while (head != null)if (head.data == oldValue){head.data = newValue;return true;}elsehead = head.next;return false;}There may be an error with the code. Answer the following:1) Design your own linked list of 4 nodes with different values2) If the code has an error, describe the issue and provide an example of calling theupdate function with values of your choice and show what the linked list looks likea.

- write a program that creates a linked list of points in an x-y coordinate system. Following are the node content of your linked list: head -> P1(0,1) -> P2(1,2) -> P3(10,11) -> P4(0,3) -> P5(17, 16) -> P6(0,0) -> P7(3,4) -> P8(16,1) ->tail Where Pz(x,y) is point z with x and y coordinates in the 2D space. Write a method searchList that recursively searches the linked list of point objects for a specified point w with x1 and y1 cooredinates: Pw(x1, y1). Method searchList should return true if it is found; otherwise, false should be returned. Use your method in a test program that creates the above list. The program should prompt the user for a value to locate in the list. For example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list: 3 4 This point is found Anothet example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list: 0 1 The point does…Given the following function to update a node in a standard linked list: public boolean update(Node head, int oldValue, int newValue) { if (head == null) return false; while (head != null) if (head.data == oldValue) { head.data = newValue; return true; } else head = head.next; return false; } There may be an error with the code.

Create a new empty linked list, insert a node (with value 1) with next pointer to null, insert a node (with value 2) at the beginning of list, insert a node (with value 3) at the end of list, remove end node.Implement linked based list and ADTs in Java, fullfilling all conditions listed below Remember to use the code images below for data attributes: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in…I could use help, me please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data.
