- implement the Selection sort on the dataset above using the Python programming language.A data set has 4 columns--index, CUSTOMER_EMAIL, Net Revenue, and Year. For each year we need the following information: New Customer Revenue e.g., new customers not present in previous year only Lost Customers New Customers Total Customers Previous Year Total Customers Current Year Please implement it using python.2. Each student at Middlesex County College takes a different number of courses, so the registrar has decided to use linear linked lists to store each student's class schedule and an array to represent the entire student body. A portion of this data structure is shown below: link Sec cr CSC16213 →HISHO 24 $||1|| 1/1234 2/2 357 CSC236/4 37 These data show that the first student (ID: 1111) is taking section 1 of CSC162 for 3 credits and section 2 of HIS101 for 4 credits; the second student is not enrolled; the third student is enrolled in CSC236 section 4 for 3 credits. s Write a class for this data structure. Provide methods for creating the original array, inserting a student's initial class schedule, adding a course, and dropping a course. Include a menu-driven program that uses the class.
- Assume there are three logical rows and four logical columns in a two-dimensional array of doublewords. What value is added to ESI to go from one row to the next if ESI is used as the row index?There are some differences between the linked list and the array but the main difference between the list and the array is a. List is a dynamic data structure while an array is also dynamic data b. Array is a dynamic data structure while a List is a static data because it has a fixed size c. List is a static data structure while an array is also a static data because it has a variable size d. List is a dynamic data structure while an array is a static data because it has a fixed sizea. Write a code for every function (e.g. insert, delete, update, create) of link list collection b. Write type of procedures and also write the difference between them
- Redraw the segment so that it does the same processes under the same conditions, but is structured.Suppose a list contains marks earned in the courses CSE110, PHY111, and MAT110 of each student consecutively in a nested list form. Your task is to take a course name as input from the user and sort the list based on the marks obtained in that course in order to finally print the names of the students in descending order of marks obtained i.e. from the student who earned the highest marks to the student who earned the lowest. For example, the list may look likelst = [ ["Alan", 95, 87, 91], ["Turing", 92, 90, 83], ["Elon", 87, 92, 80], ["Musk", 85, 94, 90] ]where for each nested list, 1st index holds the name of the student, 2nd index is total marks earned in the CSE110 course, 3rd index is PHY111 marks and 4th index is MAT110 marks. ===================================================== Hint:You may create a function for sorting, then call it every time when needed instead of rewriting the code. You may get the data in the individual lists from the given nested list.…Suppose a list contains marks earned in the courses CSE110, PHY111, and MAT110 of each student consecutively in a nested list form.
