Title: frustration abound!
Review: Anyone who has scrolled down to this half of the page is probably some disgruntled computer science student, who's had the unfortunate luck of this being assigned as their textbook. Any hope of comprehending this book will have to be due to no less than your 100% undivided attention while reading, and even if you attempt to answer the exercises, you will probably be destined to an ungratified fate because of the lack of an answer key for sale -- or you can grovel to your professor, but according to the publisher, it's strictly TOP SECRET information. I have never encountered a textbook that is more of a discouragement ... no, a retardant, to learning.
