Here, I can only see four pages of my submission. Months ago, i can see all my submission. There were about tens of pages in the past.

Is this a unknown bug? Anyone who have the same problem?

Thanks a lot.

the following link, the sumbission id is gray, i can not click to view it. My friends can not view it also.

http://www.codeforces.com/submissions/luyi0619

however, submission id before 1131907 i can see.

Could anybody help tell me why?

UPD:

It is due to a GYM bug, when a page with a gym submission, then the whole page can not be viewed. Now my second page can not be viewed. Thanks for random.johnnyh pointing it out and thanks everybody here.

I found that "lf" is ok for GNU C++ and MS C++, but not ok for C++ 0x using printf. Also, "f" works well for them.

float and double both use "f" ?

How about scanf ?

Could any body offer me some references?

First, i want to say "Happy new year to everyone!"

I have a problem of denial of judgement? The problem is http://codeforces.com/problemset/problem/75/D

I have tried 3 kinds of languages to solve it, but they are all denial of judgement...

Anybody knows why? Thanks a lot.

The contest usually takes place at 07:00PM , but there are lots of participants all over the world.

I think Codeforces should learn from Topcoder, that each contest has different time, then everyone can have a good time to take part in the game, at the same time,they don't have to stay up late.
