i wanted a book to brush up on some data structures since i've been out of programming for a few months. plus, most of my learning of these has been self taught and from the internet where there is limited (good) writings on more complex subjects such as programming. so i wanted to have a fresh perspective. not only does the book contain very useful details in many areas and to the point information (gets to the first data structure by page 14!) but the author somehow makes this stuff fun to read.the author doesn't go hugely in to depth in some areas but that's pretty much what i wanted since i am already familiar with how to use most of the stuff. very good book and i'd highly recommend it. hope this author continues with more books!
