Hey, I read your code for like 15 minutes and it seemed perfectly OK for me, then I noticed a tinny little silly mistake :

in the 34th line you have a parentheses problem, instead of x^ans > ans you have to change it to (x^ans) > ans .

Fixing that will give you AC.

PS : you could code the Gaussian Elimination without building the actual matrix (simply by applying bit operators on the array), Good Luck.

I've also been wondering why some comments are getting heavily downvoted !!!! There's NO REASON AT ALL behind such childish behaviour.

okay so if this round is going to be rated then there's no excuse to make any other round in the future unrated , I mean people who submitted 30 min before the end of the contest got stuck in the queue then got MLE and RTE on test 1 ( even worse : some of them got Compilation Error !!!) after the end of the contest , I mean if this contest will be rated then I don't see any reason which will make any future contest unrated , maybe even if we are obliged to write our solutions on paper and send them via post mail xD ...

I couldn't agree more ! We've already started to see the rating inflation ....

It's not really "mature" to blame other for your own mistakes, the round was good maybe C was a litlle bit harder than usual but look to the bright side after the editorial you will learn new approachs and techniques, there is never a "bad" round ... there is a good/bad performance and in both cases it's always an oppurtunity to learn new things and better ways to attack futur problems

Thanks . Nice contest/editorial !

Can we solve G using segment-tree ? (we search for the minimum value then we query on the second minimum on all intervals containing the first value and we update the interval that contain the maximum number of minimums and so on until we run out of reserve archers..)

Why using Floyd Warshall for an unweighted graph ? just do a BFS..

Please put stronger pretests in futur contests, We really don't want this awesome website to turn to Hackforces instead of Codeforces, this is really bad I mean I understand that this whole pretests thing is necessary due to huge number of participants but really try to make sure you put some strong pretests (sometimes a completely wrong solution can pass pretests... ) . In addition to that the hacks idea is really good but I think the hacks should not be very easy like they are now ( some people don't even read the code they just try limit input data and see if they get lucky hacking the solution )

THIS IS VERY IMPORTANT !!! I submitted my solution for problem A during the contest and it passed the pretests then I got RTE on test 49 during system test phase, after the contest I resubmitted the exact same code and I got ACCEPTED !!!! submission during contest : http://codeforces.me/contest/895/submission/32683171 submission after the contest : http://codeforces.me/contest/895/submission/32733925 PLEASE nbah CHECK THIS PROBLEM !
