Description Create an application that maintains an array of your home inventory and displays the contents of the array in a list box. For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…

python: numpy def purchases(transactions):    """    QUESTION 7    - A high-end store is trying to evaluate the total amount that customer's spend per transaction. They      want customers to spend anywhere between $130 and $150 on average.    - You need to determine whether the average number spent on each transaction per month is above, between, or      below the desired amount.    - Transactions is a numpy array containing a date, total amount earned each month, and total      number of transactions each month.    - Above: month's average amount spent per transaction > 150    - Within Range: 150 >= month's average amount spent per transaction >= 130    - Below: month's average amount spent per transaction < 130    - Return a numpy array with "Above", "Within Range" and "Below" for the average amount spent per transaction per month    - THIS MUST BE DONE IN ONE LINE    HINT: use np.where() and convert the type of each column to float     Args:        transactions…

Alphabet Random Walk• Write a program to generate a random walk that spans a 10*10 character array (The initial values of the elements are all.). The program must randomly walk from one element to another, moving one element position up, down, left or right each time. The elements that have been visited are labeled with the letters A through Z in the order in which they were visited

part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)

Q_8. Decription:- Given an array of integers, write a PHP function to find the maximum element in the array. PHP Function Signature: phpCopy code function findMaxElement($arr) { // Your code here } Example: Input: [10, 4, 56, 32, 7] Output: 56 You can now implement the findMaxElement function to solve this problems. .

Lab Activity for the students: Exercise 5: Write a program that asks the user to input 8 numbers and save them in a 2D array with 4 rows and 2 columns. The program finds the sum of all elements and prints the array in reverse order. (1 Mark ) Example : If the inputs are 12, 7, 23, 86, 40, 64, 97, 55. Then, the program will print: 55 97 64 40 86 23 7 12 Sum = 384
