What I hated about that book is that it's full of exercises (good!) but no answers are provided (bad!). I really don't understand the mentality behind providing such good exercises with no way to check your answers - and they're not the kind of problems that you can verify your answer to, either.
Often you can find some solutions to problem sets on course pages that use the book.
I agree that it would be better to provide solutions, but not all textbooks are written to be used in self-study. I don't know enough about CS to offer up any concrete recommendations, but there are math books that come with worked problems (e.g., https://www.springer.com/series/3423) and other math books that don't have worked problems (https://www.springer.com/series/666).
