g Consider a grocery online shopping application. This application allows users to shop from a contracted store. These stores can update their online store page with items, prices, coupons, and alternative item for item not always available. The user logins to their account, specify their geographical area and access the contracted stores for that area. Once a store is selected, user can shop using the store online page for items they need and select a delivery window of time. When order is submitted an employee will pick their list. Problem 3: Scrum development a) (0.9 point) Create a backlog than create a sprint plan for the online grocery application. b) (0.3 point) List 3 other activities needed for the development of the application. Problem 4 Requirements a- (0.3 point) List 6 characteristics for a good requirement. b- (1.2 point) Write 3 nonfunctional requirements for the grocery application and 3 user functional requirements and decompose those into 2 system requirements.

3. bob is arguing that if you use output feedback (ofb) mode twice in a row to encrypt a long message, m, using the same key each time, it will be more secure. explain why bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).

If an improvement creates no significant change in a product’s performance, then it is a(n) ? a0 design improvement. (there are no answer choices)

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: a. double the number. b. reverse the digits of the number. c. raise the number to the power of 2, 3, or 4. d. sum the digits of the number. e. if the number is a two-digit number, then raise the first digit to the power of the second digit. f. if the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. after performing an operation if the number is less than 10, add 10 to the number. also, after each operation determine if the number is prime. each successive operation should be performed on the number generated by the last operation. your program should not contain any global variables and each of these operations must be implemented by a separate function. also, your program should be menu driven. 7. (fraction calculator) write a program that
