You may use thedata structures and algorithm code from the lecture notes.Hint: Consider using recursion. To do so implement a private helper method that takes a Node andthen recursively calls itself to traverse the tree. The public method would call the private methodpassing the tree's root as the Node.

Java / Trees: Which node in a tree does not have a parent? Multiple chocie. center null root leaf
DATA STRUCTURE C++: Binary trees What is the definition of the public method setRootData for binary tree? Implement it using a recursive helper in a way that the resulting binary tree stayed balanced.
Use Java to create a Binary Search Tree Class with the following Operations: Insert(int n) : add a node the tree with value n. Its O(lgn) Find(int n) : find a node the tree with value n. Its O(lgn) Delete (int n) : delete a node the tree with value n. Its O(lgn) Display(): prints the entire tree in increasing order. O(n).

1. Create a Java program that prompts the user the initial choices for the Binary Search Treea. User chooses 1: Insert, User chooses 2: Delete, User chooses 3: Show BinaryTree, User chooses 4: Exit Program 2. Insertion in a tree should be such that it obeys the main properties of the binary searchtree. The basic algorithm should be:a. If the node to be inserted is greater than the existing root, move down a levelthrough the right pointer of the root.b. If the node to be inserted is lesser than the existing root, move down a levelthrough the left pointer of the root.c. Repeat this process for all nodes till the leaves are reached.d. Insert the node as the left or right pointer for the leaf (based on its value - if it issmaller than the leaf, it should be inserted as the left pointer; if it is larger than theleaf, it should be inserted as the right pointer) 3. Deletion is a bit more complicated than insertion because it varies depending on the nodethat needs to be deleted from the…
5. For the following binary tree: a. List the node numbers for traversing the tree using the preorder traversal method. b. List the node numbers for traversing the tree using the inorder traversal method. c. List the node numbers for traversing the tree using the postorder traversal method.
Write 5 functions in C++ for a binary search tree. DeleteAll() deletes all the nodes in the binary tree recurively. findNode(int item) //finds the node in the tree ITERATIVELY. countNonLeaves() takes a binary tree and counts the number of nodes that are not leaves in the given Binary Tree. OneChild() Calculate the number of nodes that have only one child in a given Binary Tree. findRange() return the range value of a Binary Search Tree. [ max(BST), min(BST) ] where max is the maximum value of the BST and min is theminimum value of the given BST. All of these functions should be called in the main and tested. Thank you.
