In java please DescriptionWrite two programs; a tester() program and a testTree().You will be making a program that will hold the following data in a data structure. The datastructure will be making is a binary search tree (BST). Your testTree() should start with havingthis methods below:1. display()- Display information of the whole tree in INORDER traversal.2. add()- Add a piece of data to your binary tree.3. delete()- Delete a piece of data from the binary tree.4. find()- Find a piece of data and print it.5. findLargest()- Find and print the largest piece of data in the binary tree.6. findSmallest()- Find and print the smallest piece of data in the binary tree.On the tester() program you should start by adding the data below:444, 555, 111, 888, 333, 999, 222, 666, 777The program should then enable the user to select the following options:1. display() The program should then enable the user to select the following options:1. display()2. add()3. delete()4. find()5. findLargest()6. findSmallest(()The program should loop the options till the user enter “000" as one of the options and theprogram should terminate.

import java.util.Scanner; public class tester{ public static void main(String[] args) {…

The program should then enable the user to select the following options: 1. display() 2. add() 3. delete() 4. find() 5. findLargest() 6. findSmallest() The program should loop the options till the user enter “000" as one of the options and the program should terminate.

C++ DATA STRUCTURES Implement the TNode and Tree classes. The TNode class will include a data item name of type string,which will represent a person’s name. Yes, you got it right, we are going to implement a family tree!Please note that this is not a Binary Tree. Write the methods for inserting nodes into the tree,searching for a node in the tree, and performing pre-order and post-order traversals.The insert method should take two strings as input. The second string will be added as a child node tothe parent node represented by the first string. Hint: The TNode class will need to have two TNode pointers in addition to the name data member:TNode *sibling will point to the next sibling of this node, and TNode *child will represent the first child ofthis node. You see two linked lists here??? Yes! You’ll need to use the linked lists
Write a program for implementing queue using linked lists, for which you should use a structure to create a node with data and the next pointer. The program should be able to insert, delete and display nodes in the queue. The user will be asked to enter his choice either to insert a node (enqueue), delete a node (dequeue), display or to exit from the program.The options for the user should be as the following:1. Insert a node (Enqueue)2. Delete a node (Dequeue)3. Display4. Exit  For example if user selected option 1 then the following should appear in the output:Enter the value to insert:Node is inserted If user selected option 2 then the following should appear in the output:Deleted Element is:  If the user selected option 3 then the program should display the elements that are available in the queue The program will keep on running and taking inputs from the user until he selects the 4th option to exit.
Computer Science JAVA Write a program that maintains the names of your friends and relatives and thus serves as a friends list. You should be able to enter, delete, modify, or search this data. You should assume that the names are unique. use a class to represent the names in the friends list and another class to represent the friends list itself. This class should contain a Binary Search Tree of names as a data field. (TreeNode Class BinarySearchTree Class FriendsList Class)

A data structure called a deque is closely related to a queue. The name deque stands for “double-ended queue.” The difference between the two is that with a deque, you can insert, remove, or view from either end of the queue. Implement a deque using arrays
In c++ , write a program to create a structure of a node, create a class Linked List. Implement all operations of a linked list as member function of this class. • create_node(int); • insert_begin(); • insert_pos(); • insert_last(); • delete_pos(); • sort(); • search(); • update(); • reverse(); • display(); ( Drop coding in words with screenshot of output as well )
C++ A program applying the topics involved in data structures (linked list, graph, array etc.) 1. User will be asked to login/signup 2. User will choose for the nearest restaurant (undirected graph?) 3. User will add to cart (from the menu list of the restaurant) 4. User will be asked for order confirmation and mode of payment (cash on delivery, card??) note: new users will have a discount 5. Invoice Using Dev c++
Student should be able to develop the programs for queue using arrays and linked list By Using C++ software. Exercise 1: Implementation of Queue using Array or Linked list Consider a real life situation. Formulate a question and then design a simulation that can help to answer it. Choose one of the following situations: • Cars lined up at a car wash • Customers at a grocery store check-out • Airplanes taking off and landing on a runway • A bank teller Be sure to state any assumptions that you make and provide any probabilistic data that must be considered as part of the scenario.
In this assignment, you will create a Linked List data structure variant called a “Circular Linked List”. The Node structure is the same as discussed in the slides and defined as follows (we will use integers for data elements): public class Node { public int data; public Node next; } For the Circular Linked List, its class definition is as follows: public class CircularLinkedList { public int currentSize; public Node current; } In this Circular Linked List (CLL), each node has a reference to an existing next node. When Node elements are added to the CLL, the structure looks like a standard linked list with the last node’s next pointer always pointing to the first. In this way, there is no Node with a “next” pointer in the CLL that is ever pointing to null. For example, if a CLL has elements “5”, “3” and “4” and “current” is pointing to “3”, the CLL should look like: Key observations with this structure: The currentSize is 3 meaning there…
Java Programming Exercise 2 Another co-worker emails you and said she developed a recursive version for doing search in a binary search tree. Here’s the code for the function: public boolean searchRecursive(Node current, int searchValue) { if (current.data == searchValue) return true; else if (current == null) return false; else if (current.data > searchValue) return searchRecursive(current.left, searchValue); else return searchRecursive(current.right, searchValue); } She says that she “keeps getting an error” but unfortunately did not say if it was a compile error or a run-time error (or both). You analyze the code and see there is indeed an error and so you reply with the following: Draw a picture of what a binary search tree would look like after inserting values of 5, 10, 8, 15, 4, 2, and 3 in that order Next, tell her why she gets either a compile time error or run-time error (or both) and…
