PRIZES

The following twenty lucky participants receive a T-shirt:

• Top 10 Indian participants.
• Random 10 from top 100 (ranks 11-100) Indian participants.

These ranks are determined from the combined unofficial rank list. People who have their Country set to India in their CF profile will qualify as Indian participants.

We are giving T-shirts to Indian participants only to avoid logistic issues that we have to face during international delivery. We apologize for this limitation, we will try our best to bring international prizes too from next year.

Thanks to NEAR for supporting this round, details can be found in this post.

Are you delighted to give programming contests but are yearning for a break from the monotonous contests? Are your friends tired of your puns and references? Can you think out of the box? If so, we invite you to the Fool's Programming Contest, as a part of Threads, Felicity IIIT Hyderabad! We have prizes worth 13K INR.

The hardest part of the problem is not programming the solution but deciphering the question, spot the hints and make some guesses to get the same perspective as the problem setters had.

Date and Time: March 25th, 2100-2300 IST
Contest Link: CodeChef FOOL2022
Registration for prizes: On the contest page

You will have eight problems and two hours to solve them. The problems are a good mix for all difficulty levels, from grandmasters to pupil. We have some hard problems, and some very easy too, and everything in between. You can try the previous fool's programming contest here.
