Implement the inordermethod in BST using a stack instead of recursion. Write a test program thatprompts the user to enter 15 integers, stores them in a BST, and invokes theinorder method to display the elements.
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.
Convert the part to recursive way in Java: public boolean search(E data) { Node<E> curr = root; int cmp; while (curr != null) { if ((cmp = data.compareTo(curr.data)) == 0) { return true; } else if (cmp < 0) { curr = curr.left; } else { curr = curr.right; } } return false; }
Write a recursive private method called countTwoEvenChilds to be included in class BinaryTree as discussed in the lectures. The method counts and returns the number of nodes having two children with even data values in the binary tree. This method is called from a public method countTwoEvenChildsBT, given as follows: public int countTwoEvenChildsBT(){ return countTwoEvenChilds(root); } Method heading: private int countTwoEvenChilds(Node<E> node)
Python has an inbuilt process, in, for doing this.For instance: x in thislist. You should not use this method
In python. 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…

Write a Java program that creates and maintains a binary search tree (BST) whose nodes are student records. Each student record (BST node) contains the student's id (String), name (String) and GPA (float). Use the student id as a key for the BST. The program starts with an empty BST and offers the following menu options to the user repeatedly until the user selects the 'Q' option (quit). A: Add a new student record to the BST. Here the user is prompted to enter the new student’s id, name and GPA. The program should display an error message if the student id already exists in the BST. F: Find a student record. Here the user is prompted to enter the id of the student to be searched. If found the program displays the student id, name and GPA, otherwise the program displays an error message. D: Delete a student record. Here the user is prompted to enter the id of the student record to be deleted. The program should display an error message if the student id is not found in the BST. P:…

Given the following recursive method, what would be the output assuming that the root is the passing value to node parameter private int unknown(Nodestnteger node) fir(node nul) return 0 else return 2*node.data + unknowntnode.left A It will return the double of the summation of the left subtree of the root node. It will return the double of the summation of the data of the root node and only the data of the left nodes of the left subtree of the root node. It will return the summation of double of the data of the root with the data values of the subtree of the root node. It will return the summation of double of the data of the root with the double of the data values of the subtree of the root node.
