To identify all the nodes that are considered to be leaves, or the nodes that do not rely on any BNodes, you may create a new method and call it findTotalleaves (). The private method takes a BNode representing the current root as an argument, but the public one does not.

To identify all the nodes that are considered to be leaves, or the nodes that do not rely on any BNodes, you may create a new method and call it findTotalleaves (). The private method takes a BNode representing the current root as an argument, but the public one does not.
Step by step
Solved in 3 steps with 1 images
- You should create a method and call it findTotalleaves (); this method will find all of the nodes that are considered to be leaves, which are nodes that do not have any BNode dependents. The public function must not take any arguments, but the private method must accept as a parameter a BNode that represents the current root.Write a deletion method for the AVLTree class that utilizes lazy deletion.There are several techniques you can use, but a simple one is to simplyadd a Boolean field to the Node class that signifies whether or not the nodeis marked for deletion. Your other methods must then take this field intoaccount.To identify all the nodes that are considered to be leaves, or the nodes that do not rely on any BNodes, you may create a new method and call it find Totalleaves (). The private method takes a BNode representing the current root as an argument, but the public one does not.
- To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class: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…In Java In this assignment, you should provide a complete CircularQueueDriver class that fullytests the functionality of your CircularQueue class that you have improved in Lab 8. YourCircularQueueDriver class should:• Instantiate a 3-element CircularQueue.• Use a loop to add strings to the queue until the add method returns false (whichindicates a full queue).• Call showQueue.• Use a loop to remove strings from the queue until the remove method returns null(which indicates an empty queue). As you remove each string from the queue, print theremoved string.Sample Run:Monsieur AMonsieur BMonsieur Cremoved: Monsieur Aremoved: Monsieur Bremoved: Monsieur C CircularQueue Class: public class CircularQueue { private String[] queue; // array that implements a circular queue private int length = 0; // number of filled elements private int capacity; // size of array private int front = 0; // index of first item in queue private int rear = 0; // one past the index of the last item…

Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…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…
- Hashing Create a method hashSetExe to use Java HashSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the HashSet with the three elements. Create a method treeSetExe to use Java TreeSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the TreeSet with the three elements. Create a hashing function that takes the string, calculate the sum of the ASCII code of each character, and return (sum%tableSize) as the index. For example, hash(“ab”, 11) returns 8, because ‘a’ is 97 and ‘b’ is 98, which adds up to 195, and 195%11 returns 8.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(I created one linked list in TestLinkedList). I've already created the class for you and have some completed method in there, 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. public void add(T after This, T info) The parameter info will be the information the new node should contain, and the new node will be added after the node that contains the parameter after This as an information. public void removeFirst() Removes the first node in the linked list. Hint: be aware of empty lists. public void removeLast() Removes…implement this method: numOccurrencesRec(LNode node, int n, int key) – This method takes as parameters a reference to the head of a linked list, a position specified by n, and a key. It returns the number of occurrences of the key in the linked list beginning at the n-th node. If n = 0, it means you should search in the entire linked list. If n = 1, then you should skip the first node in the list.
