Puzzles for Programmers and Pros

I do not like this book by two reasons: 1. I'm kind of sensitive to the puzzles like: "I put two bullets in the chambers of a six shot revolver. I point it at your head and pull the trigger. Click. You are still alive." Please calculate the probability that you'll be dead after next try. Really, if somebody asks me this question on the job interview my answer will be that I prefer to work in the other place. In the next puzzle in this book you'll ask to calculate the probability that all population on the earth will die pretty soon. 2. Author much more shows off how he can solve the puzzles, than teach you how to solve it. He is too verbose and has no respect to the reader.
