PE == AC ?

[rafagiu]

I've noticed that, at least once, I got PE but my solution was accepted and the problem appeared as "solved" in my statistics page. Later I found right in this forum that there is some sort of "accept PE".

My doubt is: is PE always "accept PE"? How can I tell the difference from such an "AC PE" and a "WA PE"? Can I start printing everything in one line and forget about spacing and such?

Thanks!

If you click on the ranklist page of a problem, you will see "Best Accepted or Presentation Error from each author" beside the ranklist. Presentation Error (P.E.) is always considered to be accepted in UVa online judge.
But PE will not be accepted in ICPC. So it's better to correct it even your PE submission is accepted here.

I don't get what you ask.

Sorry!

What I meant is printing the output of every problem solution in one line, without even bothering about formatting it with spacement and newlines.

No, this will give u WA.

Suppose the answer is:

Code: Select all

1
2
3
 

you output:

Code: Select all

123

That means your answer for 1 would be compared as 123, which is different and it will give you WA.

If the problem uses a special correction program, it is not guaranteed it will say PE on wrong formatting. However, if there is no special correction program it is sufficient to write a single space instead of any (positive) number of white spaces. But remember, the PE is accepted only in the archive, it is not accepted during a contest.
