What this forum is about

[Carlos]

This is a new forum to post every little change we make to problem descriptions, problem's input&output, important rejudges, changes in correctr programs, new problems available...these kind of things.

We just want you to know if anything has changed just by looking into here, I will not explain deeply what has changed. If there's an important change in the description I will post a warning message next to the problem with a better information.

The rejudgements section at:
http://online-judge.uva.es/problemset/rejudge.php
will also be working, so you can still check it.

If you want to make a bug report, please don't mail directly to me, do it to:
problemset@acm.uva.es
I'll answer them anyway.

I hope you like this section.
Carlos.
