Assume we have an IntBST class, which implements a binary search tree of integers. The field of the class is a Node variable called root that refers to the root element of the tree. 1) Write a recursive method for this class that computes and returns the sum of all integers less than the root element. Assume the tree is not empty and there is at least one element less than the root. 2) Write a recursive method that prints all of the leaves, and only the leaves, of a binary search tree. 3) Write a method, using recursion or a loop, that returns the smallest element in the tree.
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”…

JAVA Write a Java method named FillTree that can fill a Binary Search Tree using 10 words that areread from the user via the keyboard. The first two words should be your first name and last name.The other 8 words can be anything of your choice. The Binary Search Tree should come from themain method. The main method calls FillTree and pass it a Tree to be filled;
using java code Problem: Suppose we want to write a program for the class BinaryTree that counts the number of times an object occurs in the tree. We need to use a method with the following header, public int count (O anObject) 1. Name your class objectCounter 2. Define main method, test the program 3. Write a method using one of the iterators of the binary tree. 4. Write another method using a private recursive method of the same name NB: Can you add main method to test the code please for 2. Define main method, test the program
P1 Suppose we want to create a method for the class BinaryTree (file BinaryTree.java) thatcounts the number of times an object occurs in the tree.a. Write the methodpublic int count1(T anObject)which calls the private recursive methodprivate int count1(BinaryNode<T> rootNode, T anObject)to count the number of occurrences of anObjectb. Write the methodpublic int count2(T anObject)that counts the number of occurrences of anObject and that uses one of the iterators of thebinary tree.Compare the efficiencies of the previous the two methods count1 and count2 using big Onotation. Add your answer as a comment before the function definition P2 Suppose we want to create a method for the class BinaryTree that decides whether two treeshave the same structure. Two trees t1 and t2 have the same structure if:- If one has a left child, then both have left children and the left children are isomorphic,AND - if one has a right child, then both have right children and the right children…
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 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.
10. Given the definition of a binary tree Node, write a method that returns the height ofa given node.Class TreeNode {Int value;TreeNode left;TreeNode right;}Static int height (TreeNode position) { }** Use only the definition of a TreeNode, don’t suppose we have other built-inmethods.
Write a java class that implements a Trie of uppercase alphabetical letters. A trie is a data structure that permits efficient lookup of words in a dictionary (See figure). You may need to make two classes i.e. TrieNode and Trie. Your trie should support the following operations: i need one method in the tree prefix (trie) class which is THE ONE BELOW if you use helper method include it please: *****allWordsPrefix(String p) [return type String[] ] = this method returns all words whose prefix is ‘p’.***** the method should return and array of a given prefix, so for example if i pass the string ''TA'' into the method it should return an array with all words starts with the given prefix. please do your best i do have insert method, search and remove i got stuck in this method only
in java : you need to start implementing a class for creating and storing Binary SearchTrees (BST). Each node of this BST will store the roll number, name and CGPA of a student.The class definitions will look like:class StudentBST;class StudentNode {friend class StudentBST;private:int rollNo;string name;Student’s CGPAStudentNode* left; // Pointer to the left subtree of a nodeStudentNode* right; // Pointer to the right subtree of a node};class StudentBST {private:StudentNode* root; // Pointer to the root node of the treepublic:StudentBST(); // Default constructor}; Write a menu-based driver function to illustrate the working of different functions of theStudentBST class. The menu should look like:1. Insert a new student2. Search for a student3. See the list of students4. QuitEnter your choice:

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)
