- In c++ A company wants to store his Employees data but orderly. Because of that owner wants to use a binary search tree. Each Node must store the employee number, name, and salary double (class). Implement in java/C++ a binary search tree that stores the employees and implements the following methods: a) Include a new Employee (insert values) b) Search an employee given its number. c) Delete an employee. d) Get in-order, pre-order, post-order traversal of tree and display values.In Java I'm trying to make a Red Black Tree through inheritance with the Binary Tree I created (as provided along with the Binary Node) yet I'm having a lot of difficulty knowing where and how to start as well as how to override and even create the Insert and Remove functions for the Red Black Tree. Code and assistance in this topic will be greatly appreciated... here is the code I'm utilizing for this project. Binary Node I created: public class BinNode{private String data;private BinNode left;private BinNode right;private int height; //height fieldpublic BinNode(){data = "";left = null;right = null;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}public BinNode(String d){data = d;left = null;right = null;}public void setData(String d){this.data = d;}public String getData(){return this.data;}public void setLeft(BinNode l){this.left = l;}public BinNode getLeft(){return this.left;}public void setRight(BinNode r){this.right = r;}public…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:

- class IntBTNode { private int data; private IntBTNode left; private IntBTNode right; } Write a new static method of the IntBTNode class to meet the following specification. Make the method as efficient as possible (do not visit nodes unnecessarily). public static int max(BTNode root) // Precondition: root is the root reference of a nonempty binary SEARCH // tree. // Postcondition: The return value is the largest value in the tree.IN JAVA PLS Create a public class BinaryTreeToMap that provides a single static method toMap. toMap accepts a BinaryTree<?> and returns a Map<Object, Integer> mapping the values in the tree to the count of the times that the value appears. Our suggestion is to have toMap create the map and then call a private recursive helper method to populate it. If the tree passed to toMap is null you should throw an IllegalArgumentException. You will need to import cs125.trees.BinaryTree, as well as Map and a Map implementation (probably HashMap) from java.util. We've provided some code to get you started. For reference, cs125.trees.BinaryTree has the following public properties:Java - class IntBTNode { private int data; private IntBTNode left; private IntBTNode right; } Write a new static method of the IntBTNode class to meet the following specification. public static boolean all10(IntBTNode root) // Precondition: root is the root reference of a binary tree (but // NOT NECESSARILY a search tree). // Postcondition: The return value is true if every node in the tree // contains 10. NOTE: If the tree is empty, the method returns true.
- CODE IN JAVA You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)!Hi, I had a question about Python. I am programming a binary search tree.
