i am stuck on coordinate compression. passed all the given test cases expect last sub task (last test case-9).itās very painful. i couldnāt find anything wrong in my code. checked so many test cases. but nothing happened. can anyone help me with it. :ā( :ā(
I feel that Iām making mistake in flushing the buffer in INTERACTIVE MATRIX
Iām doing it this way.
printf(ā1 %d %dā, i, j);
fflush(stdout);
cin>>a[i][j];
is it the right way or I am doing something wrong
Is tc 31 something special in Interactive matrix question?
I got all correct except the tc 31ā¦ Can it be fault in mu algo or is it just some edge case? Please help all are correct except tc 31
Great problems. This was the first time I competed in Div 1 and it really was educational. Kudos to the setter and tester for making the problems challenging.

Why discuss @Mike when we already got a hardworking @admin tiring herself day and night for you guys to discuss about? 
Exactly, waiting for 5 mins here!
@pshishod2646, your complexity analysis is wrong. I will explain it later after the contest.
@likecs you might have seen my latest solution (the correct one)ā¦ And I am damn clear about my time complexity analysisā¦I even run my code on my PC for worst caseā¦IT DIDNāT OUTPUT ANYTHING EVEN AFTER 10 MINUTESā¦
If you want they I can send you my code along with the worst case.
@likecs If the intended solution is same as mine then let me tell you that I know that though time complexity seems O(Something) but it is much less than thatā¦But there is a corner test case for which it is really O(Something) and it time outs!!
@pshishod2645 - I think that its best to discuss this in comments section of the problem, or over mail or a private channel with @likecs , as you both can discuss to your hearts content there :). I also dont want anything like ā@pshishod2645 discussed things related to contest but wasnt banned but my friend got banned wtfā since I am actively banning people. Hope you understand my dilemma 
What I can confirm is, that the problem is solvable

Donāt ban me please 
@vijju123 I didnāt discussed anything about the problem statement or solution, I am just pointing out a bug.
OK!! I will shut my mouthā¦Humanity is getting extinct with time xD
Lol I am not saying you did anything wrong. Its just that people make a mountain out of a small matter at times. Hope you understand
@vijju123 @aryanc403 I am unable to edit my comment, if any of you can edit it (I think people with high reputation can edit otherās comment) then do it, or else I will delete that comment
