// To find out which husbands are faithful, the wives determine the following //
// protocol: Each wife behaves as follows: If there are n unfaithful husbands //
// then each of their wives knows that there are n-1 unfaithful husbands and  //
// maybe the own one, too. By induction, we can prove that if there were n-1  //
// unfaithful husbands, then these were shot at the n-1 th day. Thus, if the  //
// wives will not hear a gunshot at the n-1 th day, they will shoot their own //
// husband at the n-th day.                                                   //
//                                                                            //
// Examples:                                                                  //
//  If n=1 holds, then the wife with the unfaithful husband immediately knows //
// that her husband is the only one (since she knows that all other husbands  //
// are faithful). Therefore, she immediately shoots him at day 1.             //
//  If n=2 holds, then both their wives know the other unfaithful husband, and//
// therefore expect a gunshot at day 1. As they don't hear it, they know that //
// their own husband must also be faithful, and therefore shoot him at day 2. //
