Programming Challenges: The Programming Contest Training Manual (Repost)

Studying the challenges of problems from international programming competitions is an effective way to improve your algorithmic and coding skills and understanding.
This new programming companion uses international programming competition-type problems to motivate the study of algorithms, programming, and other topics in computer science. The book includes more than 100 programming challenges, as well as the theory and key concepts necessary for approaching them. Problems are organized by topic and supplemented by complete tutorial material. Readers gain a concrete understanding of both algorithmic techniques and advanced coding topics.

Unique features:
