Thanks, that was the reason I got RE. Now getting WA. (That reminds me of another problem I found before: WA->TL) I think I should be able to do it now.

I'm keeping getting run-time error for no reason
I kept getting runtime error even after putting a try-catch block around the whole main function!

Could anyone please point out what caused the error?

Thanks!
I never noticed that multiple datasets were possible.
However, I'm currently getting time limit. I think I can do the left myself.

I wrote this code, tested it with the sample data and some corner cases, and got correct answers. But for some reason, I got WA after submitting. Can anyone provide me a test case that my code has a bug?

Code: Select all

currently got time limit (at least better than WA)
problem was multiple cases

I think I found the reason for (part of) the bug now! (the part that automatic log in doesn't work)
everything works fine as long as I enter the board from the "electronic board" link in the uva web.
the bug happens when I click the discuss button from any problem (the button is in the uhunt).
P.S.1 ...

The problem doesn't specify that the input coordinates will be integers or floating point numbers, so, after looking at the example, I assumed that they were integers.
However, my code (which reads the input into an int and then casts it into a double) gets WA, and after modifying the code (so it ...

the "in queue" verdict looks strange to me:
it is definitely not a "queue" because it's clearly not FIFO
it shouldn't be a "priority queue" because there aren't any reasonable priorities
it isn't a "queue by received time" because sometimes two consecutive submissions from the same computer (so ...

Some times I get WA (Wrong Answer) for printing an extra newline, and sometimes for NOT printing an extra newline. I think the verdict for such outputs should be PE (Presentation Error). Also note that on http://uva.onlinejudge.org/index.php?option=com_content&task=view&id=16&Itemid=31 has mentioned ...

I also have a problem with this one, but it's NOT OK on the example test cases.
currently no idea on what is the problem
anyone please point out the bug!

I wish a moderator come and see here...

theemathas
