Hello Codeforces!
I found that the site https://sio2.mimuw.edu.pl/ contains lots of tests of Polish Olympiad in Information (POI). But I can only enter the 1t stage of the contest and download tests. When I enter the 2nd stage manually (such as https://sio2.mimuw.edu.pl/c/oi22-2/dashboard/), it gives me 403 so I can't access the contest page. How can I get access to the page and download the tests?
If it's not open for everyone, is there anywhere we can download tests of POI? I think there was a site main.edu.pl several years ago, but it seems the site is down.
Thanks everyone.
Yes, problems of POI are really good. Is there any place we can get the tests?
Submitting (site in English, statements mostly in English): https://szkopul.edu.pl/task_archive/oi/ Tests (site in Polish): https://oi.edu.pl/l/40/
Thank you very much!
Also, please keep in mind that if you are using these problems you should credit the original source.
Yes, I wrote the original source of all the problems when I used them. I just want to use them as olympiad training. Thank you for your reminder!
Hi! Seems this site only contains the tests before XXIII OI. Are there any materials of newer contests available?
Besides szkopul, not yet.
