- In fact, the trick used to solve the problem "in a beautiful way"
- (obviously, the problem with any distribution of islands and
- bridges can be solved but not necessarily in a "beautiful" way)
- remains valid if the river has a distribution of n times n-1 islands.
-
- I will post the answer next friday (if nobody can solve it).
