- in java you have to implement some basic methods for BST's (with a little twist). Each nodein the tree has a data element (an integer) and links (possibly null) to its left and right children (youcan also include parent but not compulsory).1. Sample TreeNodeclass TreeNode{int key;TreeNode left;TreeNode right;TreeNode parent; //optional}You have to implement the given functions in Binary search Tree class.2. Binary Search Trees (BST)You are required to implement a Binary Search Tree (BST) ADT (Abstract Data Type). Followingfunctionalities are expected.2.1 ConstructorCreates an empty Binary Search Tree.2.3 Inserts a new node in BST (Standard Insert)Inserts a new node in BST.2.4 DeleteDeletes a node from a BST (Standard Delete)2.5 LookupFind a value in the tree, lookup is a fancy name of find function2.6 SizeReturns the total number of nodes in a BST2.7 MaxDepthReturns the depth of the longest path in a Binary Search Tree.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.only c here is "BinaryNode.java" // BinaryNode class; stores a node in a tree. // // CONSTRUCTION: with (a) no parameters, or (b) an Object, // or (c) an Object, left child, and right child. // // *******************PUBLIC OPERATIONS********************** // int size( ) --> Return size of subtree at node // int height( ) --> Return height of subtree at node // void printPostOrder( ) --> Print a postorder tree traversal // void printInOrder( ) --> Print an inorder tree traversal // void printPreOrder( ) --> Print a preorder tree traversal // BinaryNode duplicate( )--> Return a duplicate tree /** * Binary node class with recursive routines to * compute size and height. */ class BinaryNode { public BinaryNode( ) { this( 0, null, null ); } public BinaryNode( int theElement, BinaryNode lt, BinaryNode rt ) { element = theElement; left = lt; right = rt; } /** * Return the size of the binary tree rooted at t. */ public static int size( BinaryNode t ) { if( t == null ) return…
- Java code that eliminates the binary search's node with the lowest value. returns a reference to its element from a tree. If this tree is empty, it raises an EmptyCollectionException. If the tree is empty, returning a reference to the node with the fewest values produces an EmptyCollectionException.To copy a tree, traverse the tree using an ___ traversal and add each data item visited to the new tree. inorder postorder preorder reorderThe path length of a tree T is the sum of the depths of all positions in T. In the existing class LinkedBinaryTree, provide a non-static method named pathLength that computes the path length of a tree T. Write the testing code in the main method of the class LinkedBinaryTree. You must use and update the relevant classes provided.
- A new property named search key was introduced to handle generic search keys. How may this impact the B+ tree's growth potential?// An IntTree represents a binary tree of integers public class IntTree {private IntTreeNode overallRoot; public int evenBranches() {// TODO: Your code here} public static void main(String[] args) {System.out.println(new IntTree("[2 [8 [0] null] [1 [7 [4] null] [6 null [9]]]]").evenBranches());} // Constructs a tree with default numberspublic IntTree() {overallRoot = null;} // Constructs a tree from the given text representationpublic IntTree(String s) {overallRoot = fromString(s);} // post: Prints the numbers in this tree in a pre-order fashion.public void print() {print(overallRoot);} private void print(IntTreeNode root) {if (root != null) {System.out.print(root.data + " ");print(root.left);print(root.right);}} // post: Returns true if o is an IntTree with the same valuespublic boolean equals(Object o) {if (this == o) {return true;} else if (!(o instanceof IntTree)) {return false;} else {IntTree other = (IntTree) o;return toString().equals(other.toString());}} // post: Returns a text…Java / Trees: *Please refer to attached image* What is depth of Node W in this tree?
