INSTRUCTIONS: • You are to answer this activity individually. • You are to create a Python application that makes use of inputs, outputs, and sequence structures in Python. • It must meet all of the following requirements: • The application must create a list with exactly 10 items. The contents and type of list will be up to the student (e.g. Phone Brands, Types of Shoes, Shopping Apps). The application must first display the list after which the application must remove 5 random items from the list. The application must then show the updated list with 5 of the items removed. After this is done, the application must add 7 new items to the list. These items must be completely new and not the ones that were on the list initially. The application must then output the updated list with the added items. The application must then reverse the list and then display the updated list after it has been reversed. • The application must create a tuple with exactly 10 items. The contents and type of…
Attention>>>>>>>>> project should written in C languages In the project, a student affairs information system simulation is requested to be made using structures (“struct”), linked lists (“linked list”) and files (“file”). According to this; a) Create a structure called a course. The members of this structure are code, name, instructor, term (can take Spring or Fall values), year, and a course pointer. Functions with prototype void insertCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code), char* deleteCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code) that will operate on course data structure elements, since the courses taken by the students are to be kept with a linked list. write. While writing the insertCourse() function, prevent the same student from taking the same course more than once. b) Create a structure called student. Let the members of this structure be id, name, surname, department, class (can take B.Sc., M.Sc., Ph.D.),…

Select the correct statements about the following sequence diagram: :Specific Flight cancelBooking :Booking :PassengerRole cancel deleteFromItinerary deleteFromPassengerList A. "deleteFrom Passenger List" is a result the message "cancel." B. Booking object's lifetime ends after issuing the "deleteFrom PassengerList" message. C. Actor initiates the interaction by passing the "cancelBooking" message. D. Specific Flight, Booking and Passenger Role objects are already existing when the interaction starts.
T or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming language
Based on the below code do the following tasks: EntryScreenshould be adjusted so that the when the option ‘B’ is selected from the main menu, the screen isupdated to show a bus management menu. If the option to add a bus is selected, the screen shoulddisplay options for the type of menu to be shown. The entry screens should allow the subclasses ofclass bus to be populated. Figure 3 provides an example of the expected display. look at image uploaded import java.util.ArrayList; import java.util.Collections; import java.util.Scanner; public class EntryScreen { public EntryScreen() {} public ArrayList<Planner> managePlanners(Scanner scan,ArrayList<Planner> plans, Ministry mny, ArrayList<Bus> buses) throws NumberFormatException { ReportScreen r = new ReportScreen(); char mchoice = 'c'; String menu=""; while (mchoice!='X') { String menuOptions = "[A]dd/Create planner\n[E]dit/Update planner\n";…
Process Scheduling: Select all statements below that are true The waiting time is included in the turnaround time. In interactive systems, short response times are unimportant. The time taken in an interactive program from the issuance of a command to the commencement of a response to that command is known as the response time. The response time is the time required for a particular process to complete, from submission time to completion. Throughput is the number of processes executed per time unit. The concept of virtual (run)time in the Completely Fair Scheduler is used to ensure fairness in the allocation of processor capacity.

Q1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.
Background Often, data are stored in a very compact but not human-friendly way. Think of how dishes in a menu can be stored in a restaurant database somewhere in the cloud. One way a dish object can be stored is this: { "name": "Margherita", "calories": 800, "price": 18.90, "is_vegetarian": "yes", "spicy_level": 2 } Obviously, this format is not user-readable, so the restaurant's frontend team produced many lines of code to render and display this content in a way that's more understandable to us, the restaurant users. We have a mini-version of the same task coming up. Given a list of similar complex objects (represented by Python dictionaries), display them in a user-friendly way that we'll define in these instructions. What is a "dish"? In this project, one dish item is a dictionary object that is guaranteed to have the following keys: "name": a string that stores the dish's name. "calories": an integer representing the calorie intake for one serving of the dish. "price": a float to…
Task 4. Utility classes Develop a Menu-Driven program of LinkedHashMap class using the scenario of Task 2 and perform the following operations. (15 marks) a. Create an object of LinkedHashMap class based on the scenario with explanations of the method used. b. Create a method that will allow adding an element to LinkedHashMap Class based on the scenario. The input field must be validated as necessary. c. Create a method to delete all elements in the LinkedHashMap with explanations of the method used. Task 5. Provide a detailed reflection on the following Mo0C course given in the link below. Your reflection should address the area of Executing SQL Statements using JDBC. Your write up should have an introduction to introduce the topic, an elaboration of the use of that concept within console application and concluding with your own learning experience of that course. [Maximum words: 300 words] (Attach the progress report as appendix for evidence). (10 marks)
