Hello. For our next Nordest.pm meeting, we'd like to propose a Golf Challenge. The competition will be open for Nordest.pm members until Jan 26, date of our meeting, during which we will announce the winner, who will give us a lighting talk or something to explain his solution. So far so good.
Of course, no member of Nordest.pm can submit a problem, since he would lose his right to partecipate. So I'm asking for an unpublished problem (middle level) which won't be used in other challenges until Jan 26. If you have something that you discarded for better of more difficult problems, it will be perfect. Thanks in advance. cheers, Stefano
