Can you please help me with these three questions? 1) A designator used to give a non-member function in C++ access to the private data members of a class, even though the function is not technically part of the class, is called ______ 2) The stack operation that is required when using an array implementation, but is not required when using a linked list implementation, is ___ . isFull() push() pop() peek()   3)  A mechanism in C++ that interrupts program execution when errors occur and signals the rest of the program that something unexpected has happened is a(n) ___ .   exception logic error catch phrase interception

Please be thorough with explanation   (a) Consider implementing a stack as a class that relies on a singly linked list, maintaining pointers to both the start and end of the singly linked list in the main object. You consider two possibilities. The first is to push (insert) to the beginning and pop (remove) from the beginning of the linked list. The second is to push to the end and pop from the end of the linked list. Is one of these possibilities better than the other? Briefly explain your answer.

Can you describe the difference between the limited and unbounded stack versions?

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…

Simple stack implementation please help (looks like a lot but actually isnt, everything is already set up for you below to make it even easier) help in any part you can, please be clear, thank you Given an interface for Stack- Without using the java collections interface (ie do not import java.util.List,LinkedList, Stack, Queue...)- Create an implementation of Stack interface provided- For the implementation create a tester to verify the implementation of thatdata structure performs as expected Get on the bus – Stack (lifo)- Implement the provided Stack interface ( fill out the implementation shell)- Put your implementation through its paces by exercising each of the methods ina test harness- Add to your ‘BusClient’ the following functionality using your Stack-o Create (push) 6 riders by name§ Iterate over the stack, print all riderso Peek at the stack / print the resulto Remove (pop) the top of the stack§ Iterate over the stack, print all riderso Peek at the stack / print the resulto…

Project 4: Maze Solver (JAVA) The purpose of this assignment is to assess your ability to: Implement stack and queue abstract data types in JAVA Utilize stack and queue structures in a computational problem. For this question, implement a stack and a queue data structure. After testing the class, complete the depth-first search method (provided). The method should indicate whether or not a path was found, and, in the case that a path is found, output the sequence of coordinates from start to end. The following code and related files are provided.  Carefully ready the code and documentation before beginning. A MazeCell class that models a cell in the maze. Each MazeCell object contains data for the row and column position of the cell, the next direction to check, and a bool variable that indicates whether or not the cell has already been visited. A Source file that creates the maze and calls your depth-first search method. An input file, maze.in, that may be used for testing. You…

@6 The Reference-based Linked Lists: Select all of the following statements that are true.   options:   As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions.   According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node.   According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node.   In a double-ended singly linked list, the tail reference variable provides access to the entire list.   In a circular linked list, the last node references the first node.

Suppose we have class named NumberList that holds a linked list of double values. In this section you will modify the class by adding recursive member functions. The functions will use recursion to traverse the linked list and perform the following operations: • Count the number of nodes in the list. To count the number of nodes in the list by recursion, we introduce two new member functions: numNodes and countNodes. countNodes is a private member function that uses recursion, and numNodes is the public interface that calls it. • Display the value of the list nodes in reverse order. To display the nodes in the list in reverse order, we introduce two new member functions: displayBackwards and showReverse. showReverse is a private member function that uses recursion, and displayBackwards is the public interface that calls it.
