@Someshwar Chandrasekaran yea I think you are right. because to cross river, in the last we must have one person new and other person who came back from other end. this happens only in case of three.
Solution is possible up two three persons. when you have four person in the last move you are left with one person who dont have shoe in last because it is on the other end or the two person who have already taken their chance.
