I want to organize a private contest for my friends.

I would like to put some problems from Codeforces to the contest's problemset. To avoid cheating, the problems' statements will be rewritten, because otherwise there is a risk that someone might just google the statements to get an editorial link, and that scenario is not desirable.

I don't want to write the tests for the problems myself. Is there a way to obtain the tests from Polygon?

In other words, what I am going to do is to take an existing problem from Codeforces, rewrite its statement, copy the original problem's tests and paste the tests to the "new" problem. Is the last part possible?

UPD: solved! Thanks Mike. The solution is https://mirror.codeforces.com/blog/entry/134058#comment-1199217
