Here you see a pool with six happy frogs. You must exchange the positions of the brown and green frogs, using the following rules:

a frog can only jump to an empty water lily;
a frog can only jump over at most one other frog, that has another color;
a frog can only jump forward (so the green frogs jump right and the brown frogs jump left).
