I hope andrew018.gu wins.

I think it's just two different people named Andrew Gu
And actually andrew018.gu seems to be the actual ICPC silver medalist, I can clearly see it from his CF team.
Do I understand correctly that this is your real profile, and the one specified in the table is wrong? It is taken from CPHOF.
There are two people with name Andrew Gu on CPHOF, but I think that the one listed on Hacker Cup finalists page is correct: https://cphof.org/advanced/fhc/2025
Thanks, Yury! Also, got confirmation for Andrew himself. The table is updated now.
Gonna be an epic battle between goats!!
I don’t want to sound like a broken record, but do you by any chance have information on when/how we can claim T-shirts?

For AI track, it still shows "You are not registered for the contest" despite top rank in previous round. Wanted to bump this up in case this is missed? SecondThread pkhaustov
The registration must be done now. Please make sure everything is fine.
Thanks for prompt resolution, everything looks set now!
All the best to Denisov ! 💙 💙

Good game, well played! Though my laptop crashed during changing input file name of E...
I read problem F after the contest ended, and I've really should read it during contest, because I knew the theorem needed for it, I've once wrote a preprint about it.
That was really surprising to me, considering I also wrote a preprint for it. Well, being 17 points only is a good reason to ignore (though, with my particular scores on solving C, it actually make sense for me to consider this problem instead of a 18 points one)
btw I forgot to update with you/your co-authors , but here it is preprint/paper
Konijntje once said linear time algorithm also seems to be possible, You can see the idea here.
Yes I did check it, I know that it cannot provide a linear solution as written, but it was somewhat incorporated into the third log of the solution here.
Even making the idea work for the third log was already a pain and needed lots of additional ideas (which was the ideas I had for O(n log log n)) before this operation is able to shine.
Oh I didn't know that. Good job!

tourist ORZ !!
When will we get the hacker cup tshirts?
Auto comment: topic has been updated by pkhaustov (previous revision, new revision, compare).
Just a question when will the results of round 2 will be announced.
I mean when will the option to claim t-shirts be available or any notice will come.
Because there has been no info so far
Just wondering, do others' solutions to B work without any skips? Mine seems to.
