Query: Excellent book

First is Knuth, second is Corman that brings the art of algorithms closer to earth. Then is Sedgewick. This book provides very good balance between theory and practice and lets the practitioners know that programming is a bit more than just writing "if" and "for" and that the art of algorithms is not only art but also science. This book evolved from early editions (Algorithms in C, 1990) and keeps the standard. These two volumes is the must for every serious programmer.Cons: Java code is a bit "C-ish" and makes it clear that it is easy to write C program in Java. In addition, section Geometric Algorithms from 1990 edition and other material following this section is missing in newer editions. Maybe this material will be included in Volume 3, that as rumor says, is in preparation.
