Will the round be rated for the participants?
Yes, the round will be rated! :)
I don't know if this is the right place for this but still here is my experience in last year's TCC.
Onsite round is for top 10 or top 30?
Top 10
Can someone tell me where I can find last year's questions? and perhaps sols too.

Also it clashes with codechef lunchtime. Is there something that could be done?
Hey Sorry! Can't avoid the clash :(. Will be more careful next time.
can you postpone it by 30 mins or so? even that will be great help.
Match begins in 3 hours! All the best!

What about the T-Shirts, will they be open to all or only for Indians?
I haven't given my college ID to topcoder. was there an option for it?
After we pre-register,its directing to the rules for installing the applet. So is it that we can participate only through applet or is it possible to participate through web arena too?
Both! Pre-registration is closed now! As registration is open in the arena itself :)
I am student but it showing professional in coder info.
What does it show? Can you email me? — harshit @ topcoder.com
In my topcoder profile also it's show professional
Same here. It shows me as a professional
Hey, By default it shows Professional. The feature to change that is getting added to the Topcoder Profile back again and you will be able to change that.
Thanks
"The feature to change that is getting added to the Topcoder Profile back again..."
What does this mean?
Same Here
So I do not see any form asking are you eligible or something of that sort.So how do you separate the ranklist??
We will pick up the eligible participants after the round. Only those eligible will qualify for the finals and will get the t-shirts. College IDs will help us verify.
The rank list for this round will be common for all.
Where we need to submit my college id for verification.
Am new to this topcoder thing, I am pretty confused where to code, where to hack and all stuffs, can anyone give me a gist of it?
Here's the Java Applet Guide : https://drive.google.com/file/d/1gVJZxhWYMuUNx3PfSSTkkk-b9AeJkL4j/view

I have pre-registered via the link given. Where is the contest link?
Thanks I understood the whole process.
Please check my coder type, cannot check it. id- striver_79
is n*logn*logn intended to pass on C ?
EDIT: good tests. But still some could squeeze in TL.
Don't know the intended solution but it can be solved in O(n * logn).
Yeah I solved it in nlogn using dynamic segment tree
UPD It failed system tests :(
I can be solved by just maintaining a set.
Mine also failed (used set). Tried submitting the same with vector and sorting in practice, it passed :P
Doesn't vector + sorting become O(N*logn*logn) I had a bs and in that sorting. How do you get rid of that sorting. Did you use something like sort as you get xth raindrop you put it in sorted order.
Yes the solution is N*logn*logn. But the crazy part is that it passes (max time around 1.7s) but using set it times out. TL is 3s I guess.
Can it be that during systest the server is quite busy and so it fails. and now in practice it passes? Although 1.7s seems it will easily pass
how can server be busy with 300 ppls
Yeah. Just realized it after seeing your solution.
All the best for the finals
Yeah. Mine was same. Constraints seems they wanted to fail the other one. But can randomisation create such one is my doubt.
Hope you guys enjoyed competing! Will roll out the emails for qualifications and T-shirts on Monday!
Thanks once again for competing! :)
How do I submit contest problem in practice mode?
P.S : I am new to topcoder arena, so might be a silly question!!
Go to practice rooms tab and choose the contest. More recent the contest is higher is the contest number.
In how many days, rating update takes place on TopCoder?
Ratings are updated already.
Small suggestion, can you enable registration for sometime after the round begins like how CF does it?
Got to my laptop at 8:57pm, and missed the round. This isn't the first time I missed a round because of this :/
My rating has been updated in applet but not on topcoder website. Is it normal?
Can anyone tell why does this fail system test in practice mode ? Code
I'm not really sure but I think it's because of overflow.
In "get_next" function, you are writing like "return (P_prev * M + A) % (L + 1);". But P_prev and M are int variables so it's 32bit and it makes overflow.
One of the solution is changing to "return (1LL * P_prev * M + A) % (L + 1);".
Thanks a lot!! It worked. I should take care of such silly mistake next time!
Did anyone get the mail?
We have rolled out the emails to the top 10 for finals. Once we have top 10 finalised we will be able to start emailing for the T-shirts.
