Zonal Computing Olympiad, 2010

ZCO 2010 is running on this server in two sessions on Saturday, 12 December, 2009. Follow the links on the right to log in to these contests.

Note: There will be two separate sessions of ZCO-2010, from 10:00-13:00 IST and 14:00-17:00 IST. You can write the exam in either session, but not both. If you log in to both sessions, you will be automatically disqualified.

Test data on the grader during ZCO

During ZCO, the grader will evaluate your submissions on a selected set of test inputs and report a score to you. This is intended to help you check whether your solution is correct. However, the test data on the grader is not the final data on which your problems will be evaluated. In particular, the grader has only a few small inputs, so it will only test some obvious correctness errors and will not evaluate the efficiency of your solution.

Thus, you can use the score reported by the grader to estimate whether your submission is correct, but a perfect score shown by the grader during ZCO does not guarantee that your solution will get full marks on the real test data.
