Implement a LinkedList class that stores integers using dynamic memory and a proper main program to test it. The following member functions need to be properly implemented and tested: 1. Default constructor. 2. Parmetrized Constructor. 3. Sum. 4. Average. 5. InsertAtHead. 6. InsertAtTail. 7. Delete. 8. Pop. 9. Circular. 10. Display. Sample answer is also provided.

Make a doubly linked list and apply all the insertion, deletion and search cases. The node willhave an int variable in the data part. Your LinkedList will have a head and a tail pointer.Your LinkedList class must have the following functions: 1) insert a node1. void insertNodeAtBeginning(int data);2. void insertNodeInMiddle(int key, int data); //will search for keyand insert node after the node where a node’s data==key3. void insertNodeAtEnd(int data);2) delete a node1. bool deleteFirstNode(); //will delete the first node of the LL2. bool deleteNode(int key); //search for the node where its data==keyand delete that particular node3. bool deleteLastNode(); //will delete the last node of the LL3) Search a node1. Node* searchNodeRef(int key); //will search for the key in the datapart of the node2. bool searchNode(int key); The program must be completely generic, especially for deleting/inserting the middle nodes. Implement all the functions from the ABOVE STATEMENTS and make a login and…

Send me your own work not AI generated response or plagiarised response. If I see these things, I'll give multiple downvotes and will definitely report.
