C++ Consider the following function as a property of a LinkedBag that contains a Doubly Linked List. Assume a Node has pointers prev and next, which can be read and changed with the standard get and set methods. Assume that the doubly linked list is: 1 <--> 2 <--> 3 <--> 4 <--> 5 <-->6 If you are uncertain what the above diagram depicts, it is a doubly linked list such that: The head of this doubly linked list is the node that contains the value 1. The tail of this doubly linked list is the node that contains the value 6. The 3rd node in this list contains the value 3. The contents of this list are the values 1 through 6 in sequential order. The following questions are regarding the linked list after after the test_function is run. A. The head of the list after the test_function is run contains the value: B. The tail of the list after the test_function is run contains the value: C. The 3rd node in the list after the test_function is run…

List Member Deletion Modify the list class you created in the previous programming challenges by adding a function to remove an item from the ist and by adding a destructor: void zemove (double x) : Linkedtist (02 Test the class by adding a sequence of instructions that mixes operations for adding items, removing items, and printing the list.
