This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:
- to build your skill applying computational thinking to a problem
- to assess your knowledge and skills of different programming practices
What is this problem set trying to do[edit]
I am testing your current ability to think about a problem and solve it. There isn't a right or wrong here, just demonstrating what you know. In broad strokes, this problem set requires you to:
- REALLY understand the problem
- Think about how you might solve the problem
- Create a solution to the problem
- Test if your solution works (solves the problem)
The Problem[edit]
I teach 5 classes. I am interested in creating a system to randomly call on students in my classes. I would prefer not to call on the same student twice during one class. At the end of a class, I would like to know who I called and who I did not call on. Please reflect on your computational thinking skills & ask me questions which will help you design this system.
The input[edit]
The input will be five different buttons which represent each of my five classes. For example:
- Class 1
- Class 2
- Class 3
- Class 4
- Class 5
The output[edit]
The output of this program will be:
- the first name of a student from a class, randomly selected. I will provide you with a list of first names for my students.
- you should store the students you have called in a list (even though for now, you will only select only one).
A possible solution[edit]

How you will be assessed[edit]
Your solution will be graded using the following axis:
Scope
- To what extent does your code implement the features required by our specification?
- To what extent is there evidence of effort?
Correctness
- To what extent did your code meet specifications?
- To what extent did your code meet unit tests?
- To what extent is your code free of bugs?
Design
- To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
- To what extent is your code eliminating repetition?
- To what extent is your code using functions appropriately?
Style
- To what extent is your code readable?
- To what extent is your code commented?
- To what extent are your variables well named?
