Is it rated?
Hey, we have not implemented rating system yet. Ratings would be implemented after ICPC rounds.
Also team contests can't be made rated because of some difficulties.

It hurts when you are alone (._.)
Reminder: contest starts soon!
Are all elements in the input array distinct for the second problem ?
Not necessarily.
What do you actually mean by INT_MAX ? Does it mean largest number in input is : 2147483647
I think there is some issue with one of the test files(test file 0) of problem 2 , please look into it.
INT_MAX = 2147483647
Test data looks good only.
yup , got AC finally during contest . Thanks and sorry .
"NOTE: It will be guaranteed that the cell in row n-1 and column m-1 is always of type '2' or 'x'" Samples don't satisfy this condition
We are updating the test data. As said in the announcement.
Updated test data. Rejudging all the solutions.
Will in icpc also problems sorted according to difficulty ?
No
How to solve sorted xor problem ? Do we need to do binary search ?
In Dragonado and Problems
we sort on decreasing score so here we take 6 + 4, and time is 19 + 3 = 22 which is greater than t. Can it be possible ?
Not for our problem. Did you read the constraints?
Do ICPC qualification or regionals have same difficuly as of the today's contest.
Nope. Actual rounds would be more difficult. As for these practice rounds, we need to prepare in less time and also good problems are reserved for regionals, these rounds go more on easier side.
Will the actual round also have only 5 problems? Or can there be more?
Edit: I mean the qualification round
Not yet finalized but it would be 5 or 6.
Edit: Aiming for 7 now.
Please keep 7 or 8 problems in the online round. 5 or 6 problems aren't suitable for a 2.5-hour ICPC contest. 2018's online round had 5 problems and it became a speed-solving contest.

Hey! Thanks for the suggestion. We will try to get more problems.
Are you guys preparing the problems for regionals ?
Yes, we will be preparing the problems.
Search doesn't seem to be working. I'm not able to search any team from the search bar on the standings page. Also, can you please add a college filter in the standings?
Hi we will add filtering/searching on scoreboard before next contest.
When will the prizes for ICPC Amritapuri Practice session 5 get distributed?
There was a slight delay in plagiarism checking of the solutions. We have completed that and will be forwarding the winner list to Amrita today. They will contact the winners for the prizes. Sorry for the delay.
