Ten people (five couples) go to a party and start shaking hands. You
don't shake your spouse's hand or (of course) your own. One of the
men, Jake, shouts, "Stop! How many hands did you shake?" Every person
gives a different answer. Jake's wife is the last to answer. How many
handshakes does she have?
