I am unable too process the i/o for the interactive problem.Although i know it’s a problem from a running contest but i have wasted a number of attempts already without being able to even get an extremely silly approach being passed.It would have been better if the author had provided a code snippet for reading and writing the queries.Can anyone help?
This isnt the first interactive problem. Why not search forums or check out other such interactive problems? It can help.
i have done interactive problems previously.And i am pretty sure the approach i am using is too naive to give a WA so the fault is somewhere in read/write operations.Can’t figure out anything.
Okay, I thought its your first time with the interactive problem.
In this case, issue can be anywhere…Give the problem a closer look for any details you might have missed. Thats all i can say, since contest is live atm.
Someone can definitely help out with i/o though even though the contest is live.Nothing to do with the problem’s logic i guess.

Thanks for the link,though i figured out what mistake i was making
I have got -1 time for challenge problem in the past and I have corrected it, but now I am not able to remove it. Can someone tell what are the reasons for getting -1 as the time?
As far as I can guess from my own submissions, a slow solution results in WA with time -1.00 sec.
Doing what removes it?
