Hello.

I have tried to solve the problem 11630 : Cyclic Antimonotonic Permutations, but I repeatedly got Wrong Answer.

This problem is very easy to validate my outputs, so I can ensure that my solution is correct, but Online Judge gives WA again and again !

Validation requires Special Judge but maybe It seems that some is wrong to validate output, so please identify this problem.


And I wonder though this problem is also used during the contest, but why nobody raised the question?

Thanks.

I also have a simple and provable algorithm of permutation generation, but it gets WA.
Admins! Please, check the checker!

This problem does not look that difficult, although it is strange why no one has solved it yet.

Anyway, I am bothered by this statement:

"In case there are multiple solutions, you may print any one."

How do you determine if there is more than one solution given an integer N?
