8.7 LAB: Writing append and search methods (singly-linked list)
Given main.py and a Node class in Node.py, complete the LinkedList class in LinkedList.py by writing the append() and search() methods. The search() method should return the Node whose data value matches a given key, and None if the key is not found. The search() method should also set the position of each Node searched in the LinkedList, starting with 1.
Ex: If the input is:
12 23 59 37 923 2
12
the output is:
12 found in list at position 1.
If the input is:
12 23 59 37 923 2
68
the output is:
68 not found in list.

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 () {…arrow_forwardLinked List, create your own code.

- How nodes are defined (struct node (value count left right) #:mutable #:transparent) Write in Racket (traverse n) A traversal of a BST is an algorithm for “visiting” all node in the BST. The traversal must visit each node exactly once. In the case of a linked list, a traversal is trivial since the structure is linear: start at the head, move to the next node, and stop when you reach the tail. In the case of a BST, traversal must account for multiple child nodes and keep track of which subtrees have already been visited and which have not. There are three types of traversal: in-order, pre-order, and post-order. We will only implement in-order. The in-order traversal of a BST has the property that the node values will display in ascending or sorted order. The function can be defined either recursively or iteratively. Recursion is much simpler, so we’ll stick to that.

An integer represents front * index, an integer for rear index, and an integer to keep track number of * elements in the queue. An overloaded constructor accepts an integer for * initializing the queue size, e.g. array size. An enqueue method receives an * object and place the object into the queue. The enqueue method will throw * exception with message "Overflow" when the queue is full. A dequeue method * returns and removes an object from front of the queue. The dequeue method * will throw exception with message "Underflow" when the queue is empty. A size * method returns number of elements in the queue. A toString method returns a * String showing size and all elements in the queue.arrow_forwardstruct insert_at_back_of_sll { // Function takes a constant Book as a parameter, inserts that book at the // back of a singly linked list, and returns nothing. void operator()(const Book& book) { /// TO-DO (3) /// // Write the lines of code to insert "book" at the back of "my_sll".

- Java Given main() in the ShoppingList class, define an insertAtEnd() method 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 where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Second image is ItemNodearrow_forwardJava language Write a method to insert an array of elements at index in a single linked list and then display this list.
