Query: Disappointed

I returned this book. The licensing is very restrictive. The book comes with an "Immediate License" that allows you to type the routines into your computer and use for personal and noncommercial purposes. Any other use or distribution requires the purchase of an additional license.Some of the routines (Quicksort, p 336) are not very well coded: a bunch of one letter variable names, loops that only exit on break.
