- Build a Node class. It is should have attributes for the data it stores as well as its left and right children. As a bonus, try including the Comparable module and make nodes compare using their data attribute. Build a Tree class that accepts an array when initialized. The Tree class should have a root attribute that uses the return value of #build_tree which you'll write next. Write a #build_tree method that takes an array of data (e.g. [1, 7, 4, 23, 8, 9, 4, 3, 5, 7, 9, 67, 6345, 324]) and turns it into a balanced binary tree full of Node objects appropriately placed (don't forget to sort and remove duplicates!). The #build_tree method should return the level-1 root node. Write an #insert and #delete method which accepts a value to insert/delete. Compile and submit your source code and screenshots of the application executing the application and the results based in python. Your paper should be 2-3 pages in length (not including title and references pages)Write the full Java code for Tree234Iterator.javaWrite 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
- There is no arrayTree or testTreeADT description!!!!! 1. Problem DescriptionYou are to develop a program that plays the perfect game of TicTacToe. It should never lose. Yourproject can be done in three steps of increasing complexity. Develop the Tree ADT as an array-based concreteimplementation. For the program, there is no code to start with; you are to develop everything. However, the UMLdesign and test drivers for the Tree ADT have been supplied so you can test your implementation. You canreview the sample output below to get an idea of the interaction. Create the Array-based Tree ADT. Run it with TestTreeADT.java to insure it works.package circularlinkedlist;import java.util.Iterator; public class CircularLinkedList<E> implements Iterable<E> { // Your variablesNode<E> head;Node<E> tail;int size; // BE SURE TO KEEP TRACK OF THE SIZE // implement this constructorpublic CircularLinkedList() {} // I highly recommend using this helper method// Return Node<E> found at the specified index// be sure to handle out of bounds casesprivate Node<E> getNode(int index ) { return null;} // attach a node to the end of the listpublic boolean add(E item) {this.add(size,item);return false; } // Cases to handle// out of bounds// adding to empty list// adding to front// adding to "end"// adding anywhere else// REMEMBER TO INCREMENT THE SIZEpublic void add(int index, E item){ } // remove must handle the following cases// out of bounds// removing the only thing in the list// removing the first thing in the list (need to adjust the last thing in the list to point to the beginning)// removing the last…- the constructor needs to initialize tailPtr to nullptr - insert(): modify it to update prev pointers as well as next pointers. - remove(): modify to update prev pointers as well as next pointers. Add a new public member function to the LinkedList class named reverse() which reverses the items in the list. swap each node’s prev/next pointers, and finally swap headPtr/tailPtr. Demonstrate your function works by creating a sample list of a few entries in main(), printing out the contents of the list, reversing the list, and then printing out the contents of the list again to show that the list has been reversed. Note: your function must actually reverse the items in the doubly-linked list, not just print them out in reverse order! we won't use the copy constructor in this assignment, and as such you aren't required to update the copy constructor to work with a doubly-linked list. @file LinkedList.cpp */ #include "LinkedList.h" // Header file#include <cassert>#include…
- The following class definitions to implement the Binary Search Tree is given. class Node ( public: int data; Node* left; Node* right; Node (int key) { data = key; left = NULL; right = NULL; }; class BST{ public: Node* root; BST () { root = NULL; } Node* insert (Node* root, int key); Node* search (Node* root, int key); Node* del (Node* root, int key); Node* findMin (Node* root); Node* findMax (Node* root); void inorder (Node* root); }; A. Write a program named as ProblemA_.cpp that implements the following functions using recursion. Make a menu-based implementation so that you can call each function based on the user input. insert: insert a new node in the BST Node* insert (Node* root, int key); print: prints the values of all items in the tree, using inorder traversal technique void inorder (Node* root); • search: search a node with a value in the BST Node* insert (Node* root, int key); findMinimum: returns the element with the minimum value in the BST Node* findMinimum (Node* root);…Given Class:- import java.util.*; // Iterator, Comparatorpublic class BinarySearchTree<T> implements BSTInterface<T>{protected BSTNode<T> root; // reference to the root of this BSTprotected Comparator<T> comp; // used for all comparisonsprotected boolean found; // used by removepublic BinarySearchTree() // Precondition: T implements Comparable// Creates an empty BST object - uses the natural order of elements.{root = null;comp = new Comparator<T>(){public int compare(T element1, T element2){return ((Comparable)element1).compareTo(element2);}};}public BinarySearchTree(Comparator<T> comp) // Creates an empty BST object - uses Comparator comp for order// of elements.{root = null;this.comp = comp;}public boolean isFull()// Returns false; this link-based BST is never full.{return false;}public boolean isEmpty()// Returns true if this BST is empty; otherwise, returns false.{return (root == null);}public T min()// If this BST is empty, returns null;//…given class:- import java.util.*; // Iterator, Comparatorpublic class BinarySearchTree<T> implements BSTInterface<T>{protected BSTNode<T> root; // reference to the root of this BSTprotected Comparator<T> comp; // used for all comparisonsprotected boolean found; // used by removepublic BinarySearchTree() // Precondition: T implements Comparable// Creates an empty BST object - uses the natural order of elements.{root = null;comp = new Comparator<T>(){public int compare(T element1, T element2){return ((Comparable)element1).compareTo(element2);}};}public BinarySearchTree(Comparator<T> comp) // Creates an empty BST object - uses Comparator comp for order// of elements.{root = null;this.comp = comp;}public boolean isFull()// Returns false; this link-based BST is never full.{return false;}public boolean isEmpty()// Returns true if this BST is empty; otherwise, returns false.{return (root == null);}public T min()// If this BST is empty, returns null;//…
- Consider the following bnode class that is used to build binary trees. class bnode{ public: bnode*left; bnode *right; string data; void infixprint(void); }; Write the code for the infixprint() function so that it prints the tree in infix order.Create a lazy elimination deletion function for the AVLTree class.There are several approaches you can take, but one of the simplest is to add a Boolean property to the Node class that indicates whether or not the node is designated for deletion. This variable must then be considered by your other techniques.What is the simplest approach for me to fix a Node Constructor in my Java program? The current issue is that it does not accept the Object that is supplied to it.
