Suppose there is a modern teleconferencing application used by businesses globally which has been under heavy use for a few years due to remote work and has as a result been through several evolution release cycles to improve quality and add features. Now, assume that due to a general return to in person work, use of this system has fallen to

Choose a software product you are familiar with, perform research as needed. Assuming that you were a member of the testing team for this system and that the system is nearing release, briefly explain how you argue release testing should be performed on this system. Include requirements testing, scenario testing and performance testing What kind

In games, we often put a rectangular bounding box around our sprites in the game. We can then do collision detection between, say, bombs and spaceships, by comparing whether their rectangles overlap anywhere. Write a Python function to determine whether two rectangles collide. Hint: this might be quite a tough exercise! Think carefully about all

Identify two aggregation relationships? A degree program contains several courses. A student must be able to register in a degree program. Then the student can register in courses, drop courses, and view his schedule. In addition, the student can access the lectures, and view his grades in each course. An undergraduate can register only in level

How many ways the letters of the word ALABAMA can be arranged? How many ways are possible if no two As are allowed to be successive? How many ways are possible if it is ok to have two As together but not three or more?

A DNA sequence consists of a sequence of characters drawn from an alphabet set of four letters { A, C, G, T }. How many Genome sequences of length 8 are possible? How many of them do not start with AT ? How many of them either do not start with AT or do not end with GA ?

Create a function that helps you determine the number of houses sold in a certain month. Create a function that helps you determine the average sale amount for houses with a certain number of bedrooms and in a certain month. Create a function that helps you determine the average sale amount for houses with a certain number of bedrooms available in

Fix a symmetrickey encryption scheme SE (K, E, D). We consider alternative notions of security to INDCPA below. First consider the MROR (message realor random) notion via game MRoR1 below left and MROR0 below right. proe INITIALIZE KK proc RoR(m) Return E (m) Define the MRORadvantage of A against SE as Adve (A) Pr MROR1 outputs 1 Pr MROR0

Write a program in C that will display an integer multiplication table. It will take two inputs from the user the X and Y which is the number of rows and columns for the table. For example, if the user takes input as X = 5 and Y = 8 then your program should display # 1 2 3 4 5 6 7 8 1 1 2 3 4 5 6 7 8 2 2 4 6 8 10 12 14 16 3 3 6 9 12 15 18 21 24 4
