Re: [algogeeks] Poison River
@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.

[algogeeks] Poison River
A group of N people start off on one side of a poison river. They have a pair of magic shoes which allow their feet to touch the river without killing them. They can not jump across the river or throw the shoes across the river. Each person must use the shoes exactly once to cross the river. How can the entire group get across the river? For N=3, if the people are named A,B, and C: A wears the shoes and carries B across the river. B wears the shoes to go back across the river. C wears the shoes to carry B across the river. Each person used the shoes once, and all three people ended up on the other side of the river. How can the conditions be met for N=4? N=6? N=7?

Re: [algogeeks] Poison River
For N=3, if the people are named A,B, and C: A wears the shoes and carries B across the river. is there any condition that one can carry only one with him?
