Problem Description: Q1) Write a method public static void downsize (LinkedList employeeNames, int n) that removes every nth employee from a linked list. Q2) Write a method public static void reverse (LinkedList strings) that reverses the entries in a linked list.
Multiple choice in data structures void doo(node<int>*root){ if(root !=0) { node<int>*p=root; while(root->next!=0) root=root->next; p->data=root->data; } What is this code do? a. swap the first item with the last item in the linked list b. set the first item in the linked list as the last item c. doesn't do anything because the root parameter is passed by value d. change the root item in the binary tree with the farthest leaf item

Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.

C++ program to give implementation of circular linked list and should have the following functionality. -InsertFirst ( ? ) -InsertLast ( ? ) -InsertSpecific ( ? ) -DisplayList ( ? ) -DeleteFirst ( ? ) -DeleteLast ( ? ) -DeleteSpecific( ? ) Note: solve as soon as possible
Course: Data Structure and Algorithms Language: C++ Question is well explained Question #2Implement a class for Circular Doubly Linked List (with a dummy header node) which stores integers in unsorted order. Your class definitions should look like as shown below: class CDLinkedList;class DNode {friend class CDLinkedList;private int data;private DNode next;private DNode prev;};class CDLinkedList {private:DNode head; // Dummy header nodepublic CDLinkedList(); // Default constructorpublic bool insert (int val); public bool removeSecondLastValue (); public void findMiddleValue(); public void display(); };
