    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.

      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.

"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

In Dragonado and Problems

t = 1
n, m, t = 6 4 20
p[] = 5 3 2 1 4 2
a[] = 19 3 1 3
k[] = 6 4 3 3

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?

    • its always possible to finish m/2 assignments which gives highest marks.

        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

              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.

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?

    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.
