I can only see four pages of my submissions? Anyone who have the same problem?
By luyi0619, 13 years ago, In English

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.

Why i can not view my submission?
By luyi0619, 13 years ago, In English

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.

How to read and write "double" in GNU C++ 4.6, MS C++ , C++ 0x?
By luyi0619, 13 years ago, In English

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?

Can The Contest Time on CodeForces be more flexible?
By luyi0619, 13 years ago, In English

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.
