What would be the best way to approach a question like this? Because it took me quite a while to figure out all the steps that the code takes. I feel like on the exam I should skip this kind of question, because it takes too much time for just one right answer. Do you agree? Or is there an approach that wouldn't take so much time?

Yes, if you feel a particular question is going to take a while to solve, just mark it and move on to the next question. If you have time left after finishing other questions, then you can come back to the marked question.

There are some questions in the exam that will require a lot of time. It is best to do them at the end. All questions carry equal marks, so no point in wasting too much time on one question.
