Wilk Koza Kapusta

## Description

The peasant must transport a goat, wolf and cabbage to the other side of the
river. Unfortunately, the boat can only accommodate him and one of three
passengers (goat, wolf or cabbage) at a time. In order to solve the puzzle,
following rules must be respected: a wolf with a goat (wolf eats a goat) or a
goat with cabbage (goat eats cabbage) can’t stay alone on the shore.
