4. O] The abstract data type (ADT) Set(Elm) represent sets. Accordingly, the following is a possible set of operators: new: Set in Set Elm → Bool empty Set → Bool count Set Integer add Set Elm → Set delete Set Elm → Set intersect Set x Set union Set × Set → Set create a new, empty set true iff a value is in a set true is the set is empty returns the number of values in the set adds a value to a set removes a value from a set Set returns the intersection of two sets returns the union of two sets (a) [5] Identify between the operators enumerated above a minimal set of constructors and justify your choice (b) [5] Provide axioms for the operators empty, count, and delete.

- Course: Data Structure and Algorithms Language: C++ Question is well explained Question #2Implement a class for Circular Doubly Linked List (with a dummy header node) which stores integers in unsorted order. Your class definitions should look like as shown below: class CDLinkedList;class DNode {friend class CDLinkedList;private int data;private DNode next;private DNode prev;};class CDLinkedList {private:DNode head; // Dummy header nodepublic CDLinkedList(); // Default constructorpublic bool insert (int val); public bool removeSecondLastValue (); public void findMiddleValue(); public void display(); };In HaskellZAIN IQ Asiacell Each element of A belongs to C so, .1 1 belong to C and 1 not belong to A True O False the Union of two sets A,B is the set .2 of element which belong to both A or .B True False A ={ 0,1},B ={ 2,3},the grid is {(0,2), .3 (1,1),(0,3),(1,3)} True False
- An Unsorted Type ADT is to be extended by the addition of functionSplitLists, which has the following specifications:Function: Divides list into two lists according to the key of item.Preconditions: list has been initialized and is not empty.Postconditions: list1 contains all the items of list whose keys are less than orequal to item’s key; list2 contains all the items of list whose keys are greaterthan item’s key. - Implement SplitLists as a client function of the Unsorted list ADTWrite a struct Student that has member variables: (string) first name, (int) age and (double) fee. Write the functions as described in the class for the following purposes.1. Write a c++ function to create a dynamic sorted (in ascending order according to the age)doubly linked list, where the data component of each node is an instance of the structStudent.2. Write a function to insert the instances in the linked list. You also need to write a function to find the spot for insertion of the nodes.3. Write a function to remove the node from the linked list.4. Write a function to count the elements of the linked list.5. Write a function to determine check whether an element belongs to the linked list.6. Write a function to print the linked list (from head node) on the console.7. Write a function to print the linked list (from tail node) on the console.

- User-defined ordinal kinds for data types: pros and cons? Associative arrays have pros and cons, which are discussed below.in c++ please 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 a reference/pointer of the Currency class of Lab 2. Do not make it an inner class or member structure to the SinglyLinkedList class of #2 below. A SinglyLinkedList class which will be composed of three attributes - a count attribute, a LinkNode pointer/reference attribute named as and pointing to the start of the list and a LinkNode pointer/reference attribute named as and pointing to the end of the list. Since this is a class, make sure all these attributes are private. The class and attribute names for the node and linked list are the words in bold in #1 and #2. For the Linked List, implement the following linked-list behaviors as explained in class - getters/setters/constructors/destructors, as needed, for the attributes of the class. createList method in addition to the constructor - this is…7.
