We would like to thank hjr265 and his team for this awesome platform.
We hope everyone will find the problems very interesting to solve. Good luck and have fun.
Cool! What does Toph mean, by the way?
Also, your problems are very high quality! Also, I don't think I'm at the level where I can compete there, yet... :) Keep it up!
As it's a long contest we had to make the problem set little bit harder :P But you have got 10 days. So of course you can solve many of them if you try harder :)
What are the prizes?
That is a surprise :D
Most of the problems were fairly interesting. However, the problem statements contained several unclarities. I also noticed that "Game of Rocks" was very similar to this USACO problem.
Is there a way to solve "Primary Key" without segment tree or a variant?
Sorry for all the inconvenience. We are still inexperienced. We'll keep these mistakes in mind. I don't know much about "game of rocks", but I guess it's a coincidence. As for "primary key", so far we don't think it's possible without segment tree or any other variant.
