Bitwise is a state of the art online programming contest. The contest is time constrained and posed with some of the toughest programming and algorithms challenges in a short span of 12 hours.

Bitwise was started in the year 2001 by the 4th year undergraduate students of the CSE Department, IIT Kharagpur. The contest provides programmers across the globe a platform to compete, testing their ability to develop efficient algorithms to problems within a given time constraint. Over the last five years, the contest has become extremely popular around the world. In Bitwise 2k8, over 2500 teams participated from over 50 countries.

Registration is free and open to all. Contestants solve a set of problems posted on the site using C or C++. The solutions are evaluated, not only on the basis of correctness, but also on execution time and space complexity (FAQs).
