Make a doubly linked list and apply all the insertion, deletion and search cases. The node willhave an int variable in the data part. Your LinkedList will have a head and a tail pointer.Your LinkedList class must have the following functions: 1) insert a node1. void insertNodeAtBeginning(int data);2. void insertNodeInMiddle(int key, int data); //will search for keyand insert node after the node where a node’s data==key3. void insertNodeAtEnd(int data);2) delete a node1. bool deleteFirstNode(); //will delete the first node of the LL2. bool deleteNode(int key); //search for the node where its data==keyand delete that particular node3. bool deleteLastNode(); //will delete the last node of the LL3) Search a node1. Node* searchNodeRef(int key); //will search for the key in the datapart of the node2. bool searchNode(int key); The program must be completely generic, especially for deleting/inserting the middle nodes. Implement all the functions from the ABOVE STATEMENTS and make a login and…
Consider the following linked list of the form. This list already exists, so you do not need to write the code to create the list below: struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values (see image) : Write a code segment that prints all the current values in the linked list.
o create the linkage for the nodes of our linkedlist. The class includes several methods for adding nodes to the list, removingnodes from the list, traversing the list, and finding a node in the list. We alsoneed a constructor method that instantiates a list. The only data member inthe class is the header node.use c#
In a doubly linked list the first class is Node which we can create a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. make a node object for the new element. Check if the index >= 0.If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null. implement these 3 methods: insert_at_index(), delete_at_end(), display(). use these three functions above use this to name the items 1. insert_to_empty_list()2. insert_to_end()3. insert_at_index() 4. delete_at_start() 5. delete_at_end() . 6. display() let the output be OUTPUT: The list is emptyElement is: 3Element is: 10Element is: 20Element is: 30Element is: 35Element is: 38Element is: 40Element is: 50Element is: 60 Element is: 10Element is: 20Element is: 30Element is: 35Element is: 38Element is: 40Element…
Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order:1. Create a new Node object.2. Make the data variable in the new Node object reference the object that was passed to addFirst.3. Make the next variable in the new Node object reference the object that is currently referenced in variable first.4. Make variable first reference the new Node.Test your code by running the main method in the LinkedListRunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList{ private Node first; public LinkedList() { first = null; } public Object…
please follow instructions correctly. You are required to complete the LinkedList class. This class is used as a linked list that has many methods to perform operations on the linked list. To create a linked list, create an object of this class and use the addFirst or addLast or add(must be completed) to add nodes to this linked list. Your job is to complete the empty methods. For every method you have to complete, you are provided with a header, Do not modify those headers(method name, return type or parameters). You have to complete the body of the method. package chapter02;  public class LinkedList {  protected LLNode list;   public LinkedList()  {  list = null;  }   public void addFirst(T info)  {  LLNode node = new LLNode(info);  node.setLink(list);  list = node;  }   public void addLast(T info)  {  LLNode curr = list;   LLNode newNode = new LLNode(info);  if(curr == null)  {  list = newNode;  }  else…
You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…
Consider the following linked list of the form. This list already exists, so you do not need to write the code to create the list below: struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values: first (( See image for values )) Use this linked list to perform the following actions. Declare any additional pointers, etc., if needed, to complete the code. You do not need to write any includes or using statements—just program segments. Write a code segment that creates a new node with infoData = 13 and inserts the node after the node with the value 12.
Modify following delete() function so that it takes only two arguments, first and x without trail. void delete(listPointer *first, listPointer trail, listPointer x) { if (trail) trail -> link = x -> link; else *first = (*first) -> link; free(x); }
1. According to the following LinkedList, write pseudo code for the question belowHow do you insert a node with the data, "Brandon" between the node of "Chu" and the node of "Bethany"? 2.Assume that there is a linked list that connected several names.How do you set up a "while" loop to print the whole list? 3.What is the advantage of using a LinkedList over an ArrayList?
Chu Bethany Daryl next pext next bead The above is a LinkedList. 3. Why do you not move the head node-reference and set up the p node-reference to iterate the moving from one node to the next node while you are inserting, removing nodes or printing a list? 4. What is the advantage of using a LinkedList over an ArrayList? Next
3. void insert (Node newElement) or def insert(self, newElement) (4) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.
