You are creating a binary search tree class from scratch that contains a function getRandomNode() that returns a random node from the tree in addition to insert, find, and remove. All nodes should have an equal chance of being picked. Create an
Step by step
Solved in 2 steps
- This needs to be in java. Thanks. You are to implement a binary search tree data structure. Your program should have a minimum of three classes (the node, the tree, and a driver). Your program should include the following abilities: Ability to add each name into a binary tree node – one at a time. Place each node into the tree following the general algorithm for binary tree insertion. (The minimum list of names to be used is on the next page). You may have the program load the names via a file read OR by hard code. In either case, you must enter the names 1 at a time using the “add” method you designed. Names will be read in/added in the EXACT order that they are listed. Ability to delete any name from the tree – one at a time. Ability to print out the tree in either order (alpha and reverse alpha) Ability to “search” the tree for a specific name. Return the number of probes (i.e. a look at a node). Each time you look at a node, it is considered a “probe”. Ability to “destroy”…You may find a doubly-linked list implementation below. Our first class is Node which we can make a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. We have another class called DoublyLinkedList which has start_node attribute in its constructor as well as the methods such as: 1. insert_to_empty_list() 2. insert_to_end() 3. insert_at_index() Hints: 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. 4. delete_at_start() 5. delete_at_end() . 6. display() the task is to implement these 3 methods: insert_at_index(), delete_at_end(), display(). hint on how to start thee code # Initialize the Node class Node: def __init__(self, data): self.item = data…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.
- Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. Note: Files Ch20_Ex21Data.txt and Ch20_Ex4Data.txt contain node data that you may test your program with. minimalSpanTreeType.h : #ifndef H_msTree #define H_msTree #include <iostream> #include <fstream> #include <iomanip> #include <cfloat> #include "graphType.h" using namespace std; class msTreeType: public graphType { public: void createSpanningGraph(); //Function to create the graph and the weight matrix. //Postcondition: The graph using adjacency lists and // its weight matrix is created. void minimalSpanning(int sVertex); //Function to create a minimal spanning tree with //root as sVertex. // Postcondition: A minimal spanning…Using Java, Write a program that will take an array of generic values that are in sorted order in the array, create a binary search tree, and put the values in the array into the tree. Your binary search tree should be complete (“complete” as defined in chapter 24). Or put another way, it should have the fewest number of levels and still be“complete”.Use the following array: “A”, “B”, “C”, “D”, “E”, “F”, “G”, “H”, “I”, “J”, “K”, “L”, “M”,”N”.Remember, your code is to handle generic data types, not just strings. So while I want you to use thespecified array of strings, your program should work if I choose to use an array of Integers, orCharacters. Printout the values from the tree (not the array) in a tree fashion so that I can readily see the treestructure.For the AVLTree class, create a deletion function that makes use of lazy deletion.There are a number of methods you can employ, but one that is straightforward is to merely include a Boolean field in the Node class that indicates whether or not the node is designated for elimination. Then, your other approaches must take into consideration this field.
- The program BinaryTreeTest.java prints the nodes by inorder traversal. Please add two methods printPreOrder(Node node) and printPostOrder(Node node) in the program and print the numbers by the two orders. Then please add findMax(Node node)and findMin(Node node) to find the maximal and minimal numbers respectively for the tree. Hint: to implement findMax(Node node), a recursive method is needed. If the node is empty. return 0. If the node's right sub-tree is null, return the node's value. Otherwise call findMax() recursively using the right child as the parameter. findMin(Node node) is similar, but you will focus on left child.Help in C++ please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txtWrite a method isBST() that takes a Node as argument and returns true if the argument node is the root of a binary search tree, false otherwise.Hint : This task is also more difficult than it might seem, because the order in which youcall the methods in the previous three exercises is important.Write a method isBST() that takes a Node as argument and returns true if the argument node is the root of a binary search tree, false otherwise.Hint : This task is also more difficult than it might seem, because the order in which youcall the methods in the previous three exercises is important.

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…my code works the fine the way it is, but I need to add a function for searching for a name and giving the number of probes it took to find a name - while using names that exist in the tree – and at least one that doesn’t. Show the number of probes to reach each node. I’m having a hard time figuring out how to add those. Here is my code: package minas_gil_project_2; import java.io.FileInputStream; import java.io.IOException; import java.util.Scanner; public class BinarySearchTree { private Node head; // head of list public static class Node { String data; Node left; Node right; public Node(String data) { this.data = data; this.left = null; this.right = null; } } public Node root; public BinarySearchTree() { root = null; } public void insert(String data) { Node newNode = new Node(data); if (root == null) { root = newNode;…
