Скачать или смотреть Discrete Mathematics exam question (CS at Cambridge: exam question walkthrough). Regular languages.

We solve a Discrete Mathematics question set by one of my predecessors. You get to follow my thought process while solving the question, including false starts and wrong intuitions that I later correct.

To get the most out of this content, I recommend following the advice I gave in one of the most popular videos on this channel, "Three secrets for doing well in exams" (   • Three secrets for doing well in your unive...  ). Pause this video on the text of the exam question and give yourself a maximum of thirty minutes to write a full answer on a piece of paper, without consulting books or the Internet, as if you were doing the exam. Only then should you watch the rest of this video. Doing otherwise will ruin your only chance of reaching the solution by yourself, as you will no longer be able to do it after I've told you.
