Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forward

The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value. Save the file as ArrayMethodDemoarrow_forwardWrite a program that can be used to gather statistical data about the number of movies college students see in a month. The program should perform the following steps: Ask the user how many students were surveyed. An array of integers with this many elements should then be dynamically allocated.. Allow the user to enter the number of movies each student saw into the array. Calculate and display the total and average of the values entered. Input validation: Do not accept negative numbers for input.arrow_forward
- Below is an application in which the number of days for each month in the year is stored in an array. (Forexample, January has 31 days, February has 28, and so on. Assume that the year is not a leap year.) Display 12sentences in the same format for each month; for example, the sentence displayed for January is Month 1 has 31days. Given the following pseudocode, fill in the missing lines of code (see bold portions):class MonthDaysmain() //Declarations num month num SIZE = 12 num DAYS finish declaring arraymonth = 0while month < SIZE output complete output statement month = ____________endwhilereturnendClassarrow_forwardpython: numpy def coupons(my_list, on_sale, prices): ''' QUESTION 5 It's the time of week to go grocery shopping again! Given three arrays, one of what's on sale, one of your own list, and one of the prices, return an array of the items on your list that are on sale and more than five dollars. You have MORE coupons than you have groceries on your list- make sure to only use the coupons that correspond to your list.
