Jealous husbands There are n ≥ 2 married couples who need to cross a river. They have a boat that can hold no more than two people at a time. To complicate matters, all the husbands are jealous and will not agree on any crossing procedure that would put a wife on the same bank of the river with another woman’s husband without the wife’s husband being there too, even if there are other people on the same bank. Can they cross the river under such constraints?
a. Solve the problem for n = 2.
b. Solve the problem for n = 3, which is the classical version of this problem.
c. Does the problem have a solution for n ≥ 4? If it does, indicate how many river crossings it will take; if it does not, explain why.
