Solve this fast... Code in C++:

Complete the function given below that deletes the last two nodes. Assume that this function is part of the LinkedList class and the function can access the Node *head. Do not write the main function. Do no use Item Type class. Do not call any other function from this function. Make sure no memory leak occurs. void deleteLastTwoNodes(){ Il complete this function } Example: LinkedList before: head->5->3->8 LinkedList after: head->5 LinkedList before: head->9->5->3->8 LinkedList after: head->9->5 Linked List before: head->3->8 LinkedList after: head-> Linked List before: head->8 LinkedList after: head->
