Having trouble with creating the InsertAtEnd function in the ItemNode.h file below. " // TODO: Define InsertAtEnd() function that inserts a node // to the end of the linked list" Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts ------------------------------------------------------- main.cpp -------------------------------------------------------- #include "ItemNode.h" int main() { ItemNode *headNode; // Create intNode objects ItemNode *currNode; ItemNode *lastNode; string item; int i; int input; // Front of nodes list headNode = new ItemNode(); lastNode = headNode; cin >> input; for (i = 0; i < input; i++) { cin >> item;…
Lab 20 Removing the first element in a list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Nodes. Complete the code for the removeFirst method, which should remove and return the first element in the linked list. Throw a NoSuchElementException if the method is invoked on an empty list. Use the LinkedListRunner class’s main method to test your code. Java language

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.

Create a queue, size of queue will be dependent on the user. Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue.Enqueue: Add an element to the end of the queueDequeue: Remove an element from the front of the queueIsEmpty: Check if the queue is emptyIsFull: Check if the queue is fullPeek: Get the value of the front of the queue without removing it
card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
Java language the top half is the class that contains the linked list parts the bottom half is the method i need help setting up should take two parameters "index" and "element" should be an actual method not just LinkedList.set(index, element); please and thank you!
C# Assume you have a LinkedList of Node objects. Both classes have all the normal operations shown below. Your job is to program the DeleteTail method of the LinkedList class. This method locates and deletes the last element of the linked list. You may not change its signature line. Keep your code clean, but no documentation is necessary. A good solution will be between 5 and 10 lines of code, not counting whitespace.
Apart from the main list in the list above, elements with the same value are also linked. According to this; a) Write the Generic Node class. b) Write the method that adds a new element to the end of the list. JAVA CODE
class Node: def __init__(self, e, n): self.element = e self.next = n class LinkedList: def __init__(self, a): # Design the constructor based on data type of a. If 'a' is built in python list then # Creates a linked list using the values from the given array. head will refer # to the Node that contains the element from a[0] # Else Sets the value of head. head will refer # to the given LinkedList # Hint: Use the type() function to determine the data type of a self.head = None # To Do # Count the number of nodes in the list def countNode(self): # To Do # Print elements in the list def printList(self): # To Do # returns the reference of the Node at the given index. For invalid index return None. def nodeAt(self, idx): # To Do
Write a program that creates a linked list to represent details of students. The following details must be kept for each student: SID (for Student ID) Name Address Age Gender Your program must also display a menu to perform the following tasks: Create a linked list. Note: The method to create a linked list makes use of the method insertFirst() or insertLast() or insertOrdered() Insert new nodes to the linked list. Search for details pertaining to a particular student. Delete details of a particular student. Find number of nodes in the linked list. Display information pertaining to all students. The menu options should be as follows: Create linked list Add new student Search for a student Delete a student Find number of students Print student details Exit YOU SHOULD CREATE YOUR OWN NODE CLASS, AND YOU MUST NOT USE JAVA LINKED LIST LIBRARY.
