There is a gate between each of the animal's living
areas and the common area.
Since all animals, except for the donkey, are carnivores, two
animals cannot be placed together either in the common area or
in any of the living areas.
What is the minimum number of moves that the zookeeper can make
to place all animals where they belong?
Describe every move. For example:
Move 1: Tiger into common area.
Move 2: Alligator into lion's area.
