- Assignment: Change the styles of ordered list and unordered listCENGAGE MINDTAP Programming Exercise 9-2A | Instructions The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if an ordered list contains 1, 2, 3, 4, 5, 6, 10, 11, and 12, then the mean is 6, and their median is 5. Write an application that allows you to enter nine integers and displays the values, their mean, and their median. An example of the program is shown below: Enter number 6 12 Enter number 7 14 Enter number 8 16 Enter number 9 18 You entered: 2, 4, 6, 8, 10, 12, 14, The mean is 10.0 and the median is 10 YE ا... | 16, 18 MeanMedian.java 1 +CENGAGE MINDTAP Programming Exercise 9-2A Instructions The mean of a list of numbers is its arithmetic average.

- Program Specification For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file. Functional Requirements This program must contain the following features: Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry. Display the journal - Iterate through all entries in the journal and display them to the screen. Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location. Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal. Provide a menu that allows the user choose these options Your list of prompts must contain at least five different prompts.…True or False When you create a List object, you do not have to know the number of items that you intend to store in it.Command Program Create a program that allows you to view and edit the sales amounts for each month of the current year. This program is required to use commands add, view, totals, edit, and exit. The program should use a list to store the sales data for each month with the three-letter abbreviation for the month (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, and Dec) to use as the key for each item. When the program starts, it should read the sales data inserted from the user. If the user edits the sales data, the program should edit the data If the user selects total, then the program should calculate the total sales and average monthly sales. Use functions to view sales, edit sales, calculate total, and calculate average. Please use all commands, and thank you in advance.

The program shouldstore the numbers in a list then display the following data:• The lowest number in the list• The highest number in the list• The total of the numbers in the list• The average of the numbers in the list (in python)When a list is visualized, the indices increase to the left and decrease to the right. Question 3 options: False True
- Data structures flip_matrix(mat:list)->list You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix: W R I T X H D R L G L K F M V G I S T C W N M N F Expected: W N M N F G I S T C L K F M V H D R L G W R I T X Matrix: L C S P Expected: S P L C Matrix: A D J A Q H J C I Expected: J C I A Q H A D JData structures return_growing_num_list(max:int) -> list This function will be given a single number, it should return a list of strings of numbers. Each string in the list will only contain a single number repeated an arbitrary amount of times. The number each string will contain will be equal to the current string's index+1. The number in the string should be repeated the same number of times as the string's index+1. Each number in the string should be separated by a space. This list should stop when its size equals the max number specified. Example: max = 3 output = ['1', '2 2', '3 3 3'] max = 4 output = ['1', '2 2', '3 3 3', '4 4 4 4']C++ You should create a loop which will ask user if they want to insert, delete, display and exit. Then call the corresponding method based on the user's input. The loop will only stop once user entered "Exit" Topic: LinkedList
