دانلود کتاب Programming Challenges: The Programming Contest Training Manual

There
are many distinct pleasures associated with computer programming.
Craftsmanship has its quiet rewards, the satisfaction that comes from
building a useful object and making it work. Excitement arrives with the
flash of insight that cracks a previously intractable problem. The
spiritual quest for elegance can turn the hacker into an artist. There
are pleasures in parsimony, in squeezing the last drop of performance
out of clever algorithms and tight coding.

The games, puzzles,
and challenges of problems from international programming competitions
are a great way to experience these pleasures while improving your
algorithmic and coding skills. This book contains over 100 problems that
have appeared in previous programming contests, along with discussions
of the theory and ideas necessary to attack them. Instant online grading
for all of these problems is available from two WWW robot judging
sites. Combining this book with a judge gives an exciting new way to
challenge and improve your programming skills.

This book can be
used for self-study, for teaching innovative courses in algorithms and
programming, and in training for international competition.

The
problems in this book have been selected from over 1,000 programming
problems at the Universidad de Valladolid online judge. The judge has
ruled on well over one million submissions from 27,000 registered users
around the world to date. We have taken only the best of the best, the
most fun, exciting, and interesting problems available.
