Invitation to Kaizen, an approximation coding contest

We the Programming Club at IIIT Hyderabad (along with Entrepreneurship Cell IIIT-H) are proud to present to you an approximation-style coding contest Kaizen!

Date and Time: October 28, Wednesday 21:00-23:00 IST

Get ready with your team (of upto 2) for prizes upto 15K INR! There’s prizes for random top 50 and random top 100 as well! All prizes are global, so we would recommend non-Indian users to register as well!

The contest is aimed at beginners as well as advanced participants. I can guarantee that even masters and above will find it challenging!

The tests are designed in a way that there exist multiple approaches, which you can try and achieve high scores. Detailed editorials will be released after the contest, so even if you don’t make it to the top, you’ll learn new techniques from the contest.

I would like to thank sigma_g , animesh1309, arpan_dg, nikhil_chandak,harrycoda, yoogottamk and myself for contributing to the problem statement. And special thanks to tanuj208, dk502, akshat_goyal, manish_1729, kunalserum123 and abhishek8899 for testing the initial draft of the problemset and providing a lot of helpful feedback on it.

We hope you have fun!


Reminder: contest starts in 15 minutes !
