One way to implement a queue is to use a circular linked list. In a circular linked list, the last node’s next pointer points at the first node. Assume the list does not contain a header and that we can maintain, at most, one iterator corresponding to a node in the list. For which of the following representations can all basic queue operations be performed in constant worst time? Justify your answers. Maintain an iterator that corresponds to the first item in the list. Maintain an iterator that corresponds to the last item in the list.

Write a C program to implement a queue (FIFO) of characters in a one-way, circular, linked list. One way means that each node has only one pointer, Q, (not both a rear and a front pointer), so the program must use pointers-to-pointers. Include functions to insert(), remove(), for use in main() where the user is prompted "Enter "i" to insert a new element, "r" to remove an element, "q" to quit:"

Task 3: Implement a queue through circular linked list. Develop enqueue, dequeue, status, isempty and isfull functions. Test your code in main function with 10 elements Note: for each task, you are supposed to create three files as specified in task1, i.e., implementation file, interface file and file containing point of entry. in C++

A circular doubly-linked list .(a) In a circular doubly-linked list, there is no front or end; the nodes form a full circle. Instead of keeping track of the node at the front, we keep track of a current node instead. Write a class for a circular doubly-linked list using the attached Job class as your node objects. It should have: • A private instance variable for the current node • A getCurrent() method that returns a reference to the current...

C++ Data Structures: Implement a Stack and a Queue using Linked list In this lab you will implement the functionality of a stack and a queue using a linked list. Your program must use of the declaration of the Stack and Queue class in Stack.h and Queue.h You have to implement the functionalities of queue (enq, deq, displayQueue) in a file called Queue.cpp. All the functions in Queue.cpp should follow the prototypes declared in Queue.h. Your code should make use...

(Implement a doubly linked list) The MyLinkedList class used in Listing 24.5 is a one-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new data field name previous to refer to the previous node in the list, as follows : public class Node { E element; Node next; Node previous; public Node(E e) { element = e; } } Implement a new class named TwoWayLinkedList that uses a doubly linked list...

Description The purpose of this challenge is to implement a circular doubly-linked list using a dummy node. This challenge simulates an operating system’s window manager. Requirements Write the following struct struct Window { string appname; Window *next; Window *prev; }; Create a class called WindowManager. In this class, create a private variable Window * head. This will keep track of the location of the head node. Create private variables Window * current, * dummy. current will keep track of the...

by java Implement a linked list generic queue. Remember queues are first in first out (FIFO). Use the driver to then test each of the methods. Simply download it and place it with the other source files. Create a class GenLLQueue which has the following: Internal class ListNode which contains: Instance variable data of type T Instance variable link of type ListNode Default constructor that sets both instance variables to null Instance Variables head which is of type ListNode which...
