Same. We will get the chance when you practice:)

Maybe a lot of N2, some O2, and a very small portion of CO2 and Ar. XD

Yeah, I was keeping that in mind when I wrote the comment. I was trying to say that a tester would work hard to make the pretests strong, and therefore, the pretests are likely to be strong unless he made a mistake:)

Of course! No one wants to make the pretests weak.

Wow... Questions were really tough(especially A and B). I usually solve at least 1 question in div.2 but I couldn't solve any:( Also, only two people solved F. I think this round is closer to div 1

Congratulations to Harbour Space University for their amazing rounds for the past 5 years, and also this is the 100th educational round. I hope to see more educational rounds in the future^^

There's no solution but to wait for a while:)

It's out already^^

It is because of system testing. Wait a little bit, your submission in C will also be shown as accepted:)

I used that method too!

My Submission

Why don't you just refresh the page to make the graph original? It doesn't take long to refresh the page, I mean.

This is the first global contest that I am going to participate in. Is a global contest harder than Div.2? Can you tell me the difference between a global round and other rounds? Also, is a global round rated for me?

꼭 참가하겠습니다!(I will participate in this competition!) :god: :fan:

I'm curious too lol

yeah It's being rolled back in every contest nowadays..

good questions!^^

Do you mean that I can look at the solutions in the practice contest even if I did not solve it? If I can, how can I see the solutions?
