Is it rated ?
No, This round will not be rated.
Looking forward to it.
Are there any travel reimbursements for teams going to Onsite?
We are unable to provide travel reimbursements.
We can however provide accommodations on a case by case basis.
if some team be invited to On-Site finals but can't participate, you will post T-Shirt or not ?
Sorry for my poor English !
The Laptop Bags will be shipped across India. However, the T-Shirts are for On-Site Finalists only.
So there is no interest for non-indian coder ! if you could post some T-shirt, it would be great .
Sorry for my poor English !
Yes we will definitely try and do that next time.
PS: We have tried our best to make the problems interesting..
maybe the problem is about the post cost. I know it will cost you much if you post for about 100 participants. how about postint T-Shirt for Winner or Top 3 or Top 10 ?
I agree with him
Maybe you can give t-shirt to codechef and they send it along with codechef goodies or somthing else.
I have checked for the feasibility of your suggestions. Unfortunately, We will not be able to implement it this year being so close to the contest. We have taken your suggestions into consideration and will definitely implement them next year.
Bump, Contest starts in less than an hour... Register now if you havn't.

good contest guys , really liked ding ding ding dong. Also could somebody explain how to solve the subtree problem
There can multiple ways to do it, here is one possible way:
Preprocessing: Make a Segment Tree to store frequency for incoming elements.
Start with Traversing the tree from the root and increase the frequency of each node when you visit it. Then add (val[currnode] * sumOfSegmentTree(from val[node]+1 to MAX_ELEMENT)) to your answer. Complexity: O(N LogN)
Editorials will be published soon.

Why is this contest not on the contests page of codechef?
There is a new rule from codechef that they will not show sponsored contests links in their contest page because codechef is non-profit site.
wont these problems be shifted to the practise section?
They will be shifted soon by CodeChef...
