Question 5. Legacy Code: You have been asked to improve a codebase which is two years old. Which ONE of these sets of steps would you choose to improve this legacy code? a) 1. Draw a class diagram of the system. 2. Write the minimum necessary classes from the diagram. 3. Write the tests. 4. Write just enough code to allow the tests to pass. 5. Refactor to simplify and neaten the code, remove duplication etc. b) 1. Pull the legacy code and make a repository. 2. Swap the dependencies. 3. Refactor and debug code. 4. Write tests to cover the legacy code. 5. Create fake/dummy objects for components such as databases. 6. Push the maintained code to production. c) 1. Write the tests. 2. Refactor to simplify and neaten the code, remove duplication etc. 3. Draw a class diagram of the system. 4. Write the minimum necessary classes from the diagram. 5. Write just enough code to allow the tests to pass. d) 1. Pull the legacy code and make a local repository. 2. Write test to cover the legacy code. 3. Create fake/dummy objects for components such as databases 4. Swap the dependencies. 5. Refactor and debug. 6. Push the maintained code to production.

1.Abstract classes, 2.abstract methods  3.Interfaces are three important OOP concepts. Give an example where each would be appropriate to use

in python 1. Looking at the following class definition.  What is the name of the superclass? What is the name of the subclass?   class Rectangle(BBox):   2.For this question you will be writting a subclass to the superclass written below.   You are given class Account below that has appropriate attributes and behaviors.  You will write class CheckingAccount to be a subclass of class Account that has the added or changed features   Class CheckingAccount Has a static attribute called minBalance that is initialized to 500.00 Has a consturctor that accepts a persons name and initialbalance by parameter and initializes an Account correctly using that information Includes an overridden withdraw method that will not allow you to withdraw an amount that would put your current balance below the minimumBalance. You must use the static attribute for this method for full points.  It should adjust the balance appropriately if the withdraw can be made and should make no change to the balance if the…

Matched the term or definition with the correct term: Sub Inherits specific members of another class Child 1. Abstraction 2. Base Parent 3. Derived Super 4. Inheritance A class from which another class inherits specific members 5. Interface Object-oriented principle of a class deriving properties from a previously defined class
