They have started providing some answers: https://mitp-content-server.mit.edu/books/content/sectbyfn/books_pres_0/11599/selected-solutions.pdf https://mitp-content-server.mit.edu/books/content/sectbyfn/b... There are other sources on the web with answers. For example, https://sites.math.rutgers.edu/~ajl213/CLRS/CLRS.html https://sites.math.rutgers.edu/~ajl213/CLRS/CLRS.html 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 https://www.springer.com/series/3423) and other math books that don't have worked problems (https://www.springer.com/series/666 https://www.springer.com/series/666).
