- Create an application to keep track of a list of students and their grades in a data structures course using a binary search tree.• Create a class called student that contains 2 data members: name and grade and then create a binary search tree of objects of this class. Make sure you validate the grade (A through F, and ? for in-progress grades).• Create a menu that has the following options:o Add a student -- add the student if he/she is not already in the classo Remove a student -- display “Not Found” error message if the student is not in the class.o Update the grade -- display “Not Found” error message if the student is not in the class.o Display class roster The program should use the binary tree definition. Please list all main, cpp, and hpp files. There must be a Student class, with Student.hpp and Student.cpp files. Do not use structures.this is code #include <iostream> using namespace std; struct Node { int data; struct Node *next; }; struct Node* head = NULL; void insert(int new_data) { struct Node* new_node = (struct Node*) malloc(sizeof(struct Node)); new_node->data = new_data; new_node->next = head; head = new_node; } void display() { struct Node* ptr; ptr = head; while (ptr != NULL) { cout<< ptr->data <<" "; ptr = ptr->next; } } int main() { insert(3); insert(1); insert(7); insert(2); insert(9); cout<<"The linked list is: "; display(); return 0; } i want Re-implement it on doubly linked list take in account the set-position method and the operator overload and coy constructor and destructor ? in c++AHPA #12: Movie Titles & Star Wars * * From a data file ("Lesson 14 - Movie Data"), read in data for Year, Total Gross, %± LY, Releases, Average, #1 Release for the years 1977 to 2019. * * I have decided that longer movie titles make more money.

The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…#include <stdio.h>#include <stdlib.h>#include <time.h> struct treeNode { struct treeNode *leftPtr; int data; struct treeNode *rightPtr;}; typedef struct treeNode TreeNode;typedef TreeNode *TreeNodePtr; void insertNode(TreeNodePtr *treePtr, int value);void inOrder(TreeNodePtr treePtr);void preOrder(TreeNodePtr treePtr);void postOrder(TreeNodePtr treePtr); int main(void) { TreeNodePtr rootPtr = NULL; srand(time(NULL)); puts("The numbers being placed in the tree are:"); for (unsigned int i = 1; i <= 10; ++i) { int item = rand() % 15; printf("%3d", item); insertNode(&rootPtr, item); } puts("\n\nThe preOrder traversal is: "); preOrder(rootPtr); puts("\n\nThe inOrder traversal is: "); inOrder(rootPtr); puts("\n\nThe postOrder traversal is: "); postOrder(rootPtr);} void insertNode(TreeNodePtr *treePtr, int value) { if (*treePtr == NULL) { *treePtr = malloc(sizeof(TreeNode)); if (*treePtr != NULL) { (*treePtr)->data = value;…

Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation. In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer.
