@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.

Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference) void isEmpty() This method will return true if the linked list is empty, otherwise return false. void clear() This method will empty your linked list. Effectively, this should and already has been called in your destructor (i.e., the ~LinkedList() method) so that it will deallocate the nodes created first before deallocating the linked list itself.
Implement the following function using C++ remove_redundant() This method will clear out the duplicate numbers in your linked list. It is also imperative that you will use an instance of this Linked List class to hold the numbers that you have already checked and use the methods in this instance. In the example 10 -> 10 -> 20 -> 30 -> 10, calling remove_redundant() will remove the other 2 10's that occurred later, hereby making the list 10 -> 20 -> 30. Limitation: You cannot have a nested loop here nor use methods that employ loops as the performance of our linked list will suffer.
Need help only part 2. Thank you! In this assignment, you will create a Linked List data structure variant called a “Circular Linked List”. The Node structure is the same as discussed in the slides and defined as follows (we will use integers for data elements): public class Node { public int data; public Node next; } For the Circular Linked List, its class definition is as follows: public class CircularLinkedList { public int currentSize; public Node current; } In this Circular Linked List (CLL), each node has a reference to an existing next node. When Node elements are added to the CLL, the structure looks like a standard linked list with the last node’s next pointer always pointing to the first. In this way, there is no Node with a “next” pointer in the CLL that is ever pointing to null. For example, if a CLL has elements “5”, “3” and “4” and “current” is pointing to “3”, the CLL should look like: Key observations with this structure:…
linked_list_stack_shopping_list_manager.py This is a file that includes the class of linked list based shopping list manager. This class contains such methods as init, insert_item, is_list_empty, print_item_recursive_from_top, print_items_from_top, print_item_recursive_from_bottom, print_items_from_bottom, getLastItem, removeLastItem. In addition, this class requires the inner class to hold onto data as a linked list based on Stack. DO NOT use standard python library, such as deque from the collections module. Please keep in mind the following notes for each method during implementation: Init(): initializes linked list based on Stack object to be used throughout object life. insert_item(item): inserts item at the front of the linked list based on Stack. Parameters: item name. is_list_empty (): checks if the current Stack object is empty (ex. check if head is None). print_item_recursive_from_top(currentNode): a helper method to print linked list based on Stack item recursively. Note:…
Programming in C: Challenge 1: Create and Print a Doubly Linked List In class, I briefly mentioned how to create a doubly linked list (a linked list with two directions: forward and backwards). This task challenges you to create a doubly linked list of 5 nodes. If your nodes were called n1, n2, n3, n4 and n5 (which they shouldn’t, please give them original names), your list should be linked as follows: We discussed what "start" and "end" should be. Then, also in main, you will have to print the list forwards by taking advantage of the arrows pointing to the right. You will also have to print it backwards taking advantage of the arrows pointing to the left. Again, everything must be done in main. Hint: look at the way in which I printed the singly linked list in class. In other words, if your nodes had the values: n1=1, n2=2, n3=3, n4=4 and n5=5; your program should print:1 3 5 2 4 (forwards) and 4 2 5 3 1 (backwards). Please give different values to your nodes, they should not have…

(Circular linked lists) This chapter defined and identified various operations on a circular linked list.a. Write the definitions of the class circularLinkedList and its member functions. (You may assume that the elements of the circular linked list are in ascending order.)b. Write a program to test various operations of the class defined in (a).

JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…
