(Greedy Gift Givers A group of NP (2 ≤ NP ≤ 10) uniquely named friends has decided to exchange gifts of money.

Your goal in this problem is to deduce how much more money each person gives than they receive. The rules for gift-giving are potentially different than you might expect. Each person sets aside a certain amount of money to give and divides this money evenly among all those to whom he or she is giving a gift. No fractional money is available, so dividing 3 among 2 friends would be 1 each for the friends with 1 left over-- that 1 left over stays in the giver s "account". In any group of friends, some people are more giving than others (or at least may have more acquaintances) and some people have more money than others. Given a group of friends, no one of whom has a name longer than )
