Algorithms by Robert Sedgewick

Algorithms by Robert Sedgewick
This book presents an interesting challenge. It talks about algorithms yet it does not present algorithms, nor does it define algorithm as anything more than a "problem-solving method suitable for implementation as computer programs[p.4]." Instead, it exhibits programs which are the implementations of algorithms and discusses them as if the algorithm is apparent. The reader is left with the challenge of learning to discriminate between what is essential about an algorithm, and how to preserve that in an implementation, versus what is inessential to the algorithm and introduced on account of the implementation and the use of particular programming tools.
