in java please use comments explaining when possible! 1. Implement the inner class InorderIterator in the BinaryTree class.Your implementation must use the parent reference. You cannot userecursion or an additional data structure such as a stack or a linkedlist 2. The string representation for the tree is an in order representation.The constructor that is passed 4 strings expects the string representation of the tree and strings that represent open, close and empty. In the examples discussed in class open, close and empty were (, ( and ! respectively. Tokens in the string representation of the tree are separated by white space. 3. make sure to follow what the comments are saying as well thank you!!
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.

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. Write a method, using recursion or a loop, that returns the smallest element in the tree.
Implement the following methods in “BST.java” class: /** Return the height of this binary tree*/ public int height() { // Left as exercise return 0; } /** BreadthFirst traversal from the root */ public void breadthFirstTraversal() { // Left as an exercise } (Implement inorder traversal without using recursion) Implement the inorder method in BST using a stack instead of recursion. Implement preorder traversal without using recursion) Implement the preorder method in BST using a stack instead of recursion. (Implement postorder traversal without using recursion) Implement the postorder method in BST using a stack instead of recursion.

Answer the given question with a proper explanation and step-by-step solution. Write a recursive method(Code ) static void mirrorTree(node root) This will take a tree as input and then change the tree such that it becomes a mirror of itself. We have the following methods implemented(you can use them and assume we coded somewhere else): getLeft(), getRight(), setLeft(), setRight(), getValue(). All the values in a node are integers. [Hint: Use them, and think how you would write when the tree only has 2 children ] Example:
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…
