P1456 Monkey King

Once in a forest, there lived N aggressive monkeys. At the beginning, they each does things in its own way and none of them knows each other. But monkeys can't avoid quarrelling, and it only happens between two monkeys who does not know each other. And when it happens, both the two monkeys will invite the strongest friend of them, and duel. Of course, after the duel, the two monkeys and all of their friends will know each other, and the quarrel above will no longer happen among these monkeys even if they have ever conflicted. Assume that every money has a strongness value, which will be reduced to only half of the original after a duel(that is, 10 will be reduced to 5 and 5 will be reduced to 2). And we also assume that every monkey knows himself. That is, when he is the strongest one in all of his friends, he himself will go to duel.
