I think the links for last 24 hours do not work properly. I'm sure though but it seems it doesn't show all post of last 24 hours. About the open source software. Don't hold such radical concepts. Though I never contributed in anyone, I've used quite a lot. There are so many opensource and fantastic ...

I also think there is some problem with the search. Many times I haven't found posts regarding a problem though the number of the problem was on the subject of the post. Can someone explain if its a bug or there is something we are missing about the search facility of the board. Anyone enlightened :)

Here's an explanation how the one-dimnentional problem can be solved in O(n) say for an array [x1, x2, ..., xn] you need to find the maximum sum of consecutive elements. Say you start with an answer zero. You run a loop to add up the numbers. If the sum gets bigger than your answer update it. But if...

This is surely a good idea. But the judge's health may be of concern.

But if they can do it..... well that's another feather of glory in their hat
and we all know they have many.

Good luck to uva TEAM with this one.

Shariar bhai You are absolutely right. There will always be some problems with higher time limits & you cannot do anything about it. But for a contest of 8/10 problems you can set lower time limits say for 5 problems that will imrove the response time tremendously. And surely Upgrade of the system i...

Its a tough job being a problem setter let alone an unpaid one. I've always wanted to become one just for the reason that its so demanding. Your understanding of the topic is important, correct coding is essential, you have to understand what can be the critical inputs and how to generate enough of ...

cheating & not cheating

If you let others to force you to cheat My Question is WHO WINS? And its really frustating to have all these 0.000 at the top of problems. Rather then having all those rejudging by changing input range they should've made permutations to get this rubbish out of the ranklist. When I was a new contest...

My ranklist is pretty messed up

After the massive rejudgement it seems all of my friends ranklist has become stable but not mine. My solved number may be accurate (currently at 420+) but the list is all messed up. Many of the problems that I solved are not seen in my ranklist. It is very problematic for me to exactly remember whic...

You should get RTE for your code. But I've learned recently that RTE's for slight invalid memory access often results in WA. Check this out int image[28][28] and for (i = 0; i <= 28; ++i) for (j = 0; j <= 28; ++j) image[i][j] = 0; You are accessing "image[28][28]" :( which is an invalid memroy locat...

Why is everyone making such fine input of mixing upper/lower case character. The problem spec is clear in saying lowercase alphabet. Hint: if you are killing yourself with LCS or can't understand the problem Its as easy problem as counting character frequency. :D Did I give away TOO MUCH. :D :D

I think "rjhadley" got a point. I think out of my 400+ ACs all are less then 10K. I think >5k s are less than 20. And if you don't mind "rjhadley" for which problem you got 20K code? :D And to the administrator why is the limit as high as 40K. I know ICPC is not about compact code but 40K seems a me...

Sometimes they do increase the limit for rejecting brute-force solution.
But nowadays its almost useless with so many problems to solve. I don't
mind some people getting away with inefficient solutions of some problems.
