11630 - Cyclic antimonotonic permutations

Postby r2ro » Wed Oct 28, 2009 1:17 am

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?
