- Add courses to the cart: Customer will only be able to add a course if the title is in the master’s list.Once added, the course name and its price need to be added to a shopping cart list, the information -title and price - needs to be separated (as in master list) by any delimiter of your choice (like: colon,space, dash etc). Customer should be able to view the shopping cart list after adding a course. Delete a course from cart: Customer will enter the name of the course and the program will lookfor the course in the shopping cart list to be deleted from. View the shopping cart list after deletion. Check out course: Customer should be able to view the list of the courses and their individualprice that are being selected by the user, then view the total price of all the courses in theshopping cart. Again, you need to use a for loop to iterate over the shopping list, separate the titleand price and view the information as shown in sample I/O. Directly printing the list will…searchStudent: searches the studentsList by idNum, passed as parameter. If the object is found, it returns its location in the studentsList, else returns -1.Computer Science Javascript populateSelectMenu function The function populateSelectMenu should exist. The function populateSelectMenu should return undefined if it does not receive users data. The function populateSelectMenu selects and returns the select menu. The function populateSelectMenu receives the option elements from createSelectOptions and appends them to the select element.

Allow for the graph to display 10 degrees above the highest max and 10 degrees below the lowest minimum temperature.

- Unique Values This function will receive a single map parameter known as a_map. a_map will contain a single letter as a string and numbers as values. This function is supposed to search a_map to find all values that appear only once in a_map. The function will create another map named to_ret. For all values that appear once in a_map the function will add the value as a key in to_ret and set the value of the key to the key of the value in a_map (swap the key-value pairs, since a_map contains letters to numbers, to_ret will contain Numbers to Letters). Finally, the function should return to_ret. Signature: public static HashMap<String, Integer> uniqueValues(HashMap<Integer, String> a_map) Example: INPUT: {0=M, 2=M, 3=M, 5=M, 6=n, 7=M, 9=M}OUTPUT: {n=6} INPUT: {0=A, 1=c, 2=c, 4=c, 5=a, 8=Q, 9=c}OUTPUT: {A=0, a=5, Q=8}# Create Custom Transformer Create a custom transformer, just as we did in the lecture video entitled "Custom Transformers", that performs two computations: 1. 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. Keep…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.
