OJ Board

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Maybe my english is not good enough as you didn't understand my
problem. I know some of my problems got cut in rejudgement and
thats fine.

The problem is some of the problems still ACCEPTED are not shown in
my AuthorStatus page. It doesn't show any of my 106 volumes solved
problems and it doesn't ...

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 ...

I have made some post ragarding this topic and I've always
opposed this vast rate of rejudging.

But please everyone at UVA, don't get me wrong. Programming
Contests has been such a great part of my education life & my life
as a whole. It has made me realize & learn so many things. I have
meet ...

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 ...

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 ...

I got compiler error in the school contest.

This is the error I got
g++: 00000162_PC.c: No such file or directory
g++: No input files

But it was actually a name conflict. I used a variable name max
changing which got me AC. I am also using vector but I am not
using the statement "using namespace ...

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.
