The contents of the linked stack L_S and linked queue L_Q are swapped in both operations. While WHAT_IS_COOKING1 exchanges the data items of the lists, WHAT_IS_COOKING2 just manipulates the pointers and so appears more elegant.

A linked stack is a: (A) Single linked list in which the first node of the linked list is the top of the stack. B Single linked list in which the last node of the linked list is the top of the stack. Doubly linked list in which the first node of the linked list is the top of the stack. D) Doubly linked list in which the last node of the linked list is the top of the stack.
The insert function first checks if the list is empty then head is updated, if the list is not empty then a new node is inserted at the tail. The delete function deletes the given node (temp). This temp node can be anywhere in the list. Your task is to update the insert and delete function code so that it implements the stack rule. i-e last in first out. The insert function should only allow insertion at head and the delete function should only pop the last inserted element (no parameter to be passed to the delete function). #include <iostream> using namespace std; class Node{ public: int data; Node *next; }; class List{ public: Node *head; List(){ head = NULL; } void insert(int data){ Node *nn = new Node; nn->next = NULL; nn->data = data; if(head==NULL){ head = nn; cout<<"Node inserted successfully at head"<<endl; } else{ Node *temp…

implement the algorithm in C++ program. Algorithm to Linked List Creation Algorithm: (ITEM), [ Here the initial value of FRONT & REAR are NULL ] Step 1. Create dynamic NODE to store (Info and Next) for the next node and store its address into NewNode pointer [Insert ITEM in newly created Node for QUEUE.] Step 2. Set NewNode -> Info = ITEM and NewNode -> Next = NULL Step 3. If REAR = NULL then: Set REAR and FRONT both = NewNode [ First Node Enqueued ] Else Set REAR -> Next = NewNode Set REAR = NewNode [ End of If Structure ] Step 4. End.
