Title: excellent programming manual
Review: It is well known that programming is more of an art than a science. The best way to obtain proficiency in this subject is to try your hand at constructing algorithms for many different problems, and the present book suits this objective admirably. The problems, coming as they do from several programming contests, are very varied, challenging and often humorous. A very important feature concerning this book is that after obtaining a tentative solution, one can try its correctness and efficiency by submitting the program to a web page, where a checking robot will analyze it automatically. The book is very reasonably priced and undoubtely it will belong in the library of every scientific programmer.
