public class Node { int key; Node left, right, parent; public Node() {} public Node(int num) { key = num; left = null; right = null; parent = null; } } The most important thing is that a node as an object has four attributes: key, left, right, parent. Key holds the value of the node. Left and right refer to the left and right children nodes. Parent refers to the parent node. Please design a class named BST and include the following attributes/methods: Insert: This method accepts one parameter, the target value (an integer), and will add a new node with that value into the Binary Search Tree. This method returns the root of the updated Binary Search Tree. public Node insert(int target) Search: This method accepts one parameter, the target value, and returns a boolean. If the target value is found, this method returns true, otherwise false. public boolean search(int target) Delete: This method accepts one parameter, the target value, and will…

Circular Queue: A circular queue is the extended version of a regular queue where the last element is connected to the first element. Thus forming a circle-like structure. Create a C++ generic abstract class named as CircularQueue with the following: Attributes: Type*arr; int front; int rear; int maxSize; Functions: virtual void enqueue(Type) = 0; Adds the element of type Type at the end of the circular queue. virtual Type dequeue() = 0; Deletes the first most element of the circular queue and returns it. PLEASE USE C++

Design an inventory class that stores the following members: serialNum: An integer that holds a part's serial number. manufactYear: An integer that holds the year the part was manufactured. lotNum: An integer that holds the part's lot number. The class should have appropriate member functions for storing data into, and retrieving data from, these members. Next, design a stack class that can hold objects of the class described above. Last, design a program that uses the stack class described above. The program should have a loop that asks the user if he or she wishes to add a part to inventory, or take a part from inventory. The loop should repeat until the user is finished. If the user wishes to add a part to inventory, the program should ask for the serial number, year of manufacture, and lot number. The data should be stored in an inventory object, and pushed onto the stack. If the user wishes to take a part from inventory, the program should pop the top-most part from the stack…
