Thanks @roll_no_1 for your feedback. Sure, next time we will try to scale the event further up and get it rated for all.
Yeah, maybe the background stories (Theme: Fullmetal Alchemist) did make the problem statements somewhat long. However, we added illustrations wherever required to make the problem very clear. We will work on improving this in the next iteration.
Thanks @chaos . We will work on keeping statements concise next year.
For the corner cases, CodeChef team did really help us a lot for strong test files in the contest.
