The letuce, the wolf and the sheep.

A shepherd wants to cross a river. He travels with a sheep, a wolf and a letuce. He has got a boat; but in this boat he can carry only one element from one to another bank. How can he cross the river? You should consider that:

• The wolf eats the sheep if the shepherd lets them alone.
• The sheep eats the letuce if the shepherd lets them alone.

Good luck!! We will solve the problem tomorrow.
