Tired of ACing problems? Bored of seeing green Accepted all over your submissions page? Want something more adventurous?
What if we gave you the complete solution, and challenged you to then get an AC? Confused? We are proud to invite you to DeCode 2020, as a part of Threads, Felicity IIIT Hyderabad! The contest will be held on Feb/10/2020 18:00 (Moscow time). We will have prizes for top three Indian participants.
You'll be given problems and their buggy solutions. Your job will be to figure out on what test cases the buggy solution fails, and also fix the buggy solution itself. The solutions are exclusively written in C++.
You will have eight problems and two hours to solve them. The problems are a good mix for participants from international masters to pupil, but of course, we welcome everyone to participate!
Thanks to the setters: night_fury208, AnimeshSinha1309, madlad, Arpanet, ishita_3110, pragunsaxena, and me, sigma_g and the testers: dixitgarg, ninja_28, akshat_goyal, Horcrux1729, and b00merang. Special thanks to MikeMirzayanov for the wonderful Codeforces and Polygon systems for making this contest possible!
We'll post an editorial in this thread after the contest is over. We hope you'll enjoy it!
