First of all, Merry Christmas, Codeforces!!!

In various international contests (eg IOI) there is such a type of problem as problems with open tests. Their essence lies in the fact that the participant is given an archive of tests, and in response they need to send not a code, but an archive with answers to these tests. These answers can be received in any way, even by hand, the only condition is that this must be done before the end of the contests. Points are awarded according to some formula, based on how good the answer is.

Similar contests have already been held at Codeforces: in the problems it was necessary to send a text file containing the answer. An example of such a contest: ICPC Challenge 2020: Practice. However, it seems that such contests cannot be held by ordinary Codeforces users, since Polygon does not allow creating problems with open tests.

I consider this a serious flaw. Polygon is a very powerful and versatile platform for developing problems, but the ability to create problems with open tests, in my opinion, is really lacking. It would be really great if MikeMirzayanov would implement this.

P.S. Maybe the ability to add tasks with open tests was available all this time, and I accidentally missed it? If this already exists on Polygon, please write about it in the comments.

I also faced this problem when preparing training competitions. I had to send the code that outputs the answer to the test! This is hyper inconvenient because there is a limit on the size of the code we can send.

It is surprising that it is still impossible to create problems with open tests on polygon!

Perhaps this still cannot be done, since memory problems may occur!

Then I see no problem just not saving the file that the participant sent!
