Question

I have a programming exam this weekend. It is only one question that is asking to build an application. The final application must be based upon strategy pattern. I can provide an example of the question and what the answer should look like. Additionally, what my notes are regarding strategy pattern. It is a smaller scope application, so it shouldn’t be too difficult. Please reach out if you have any more questions.
