Suppose there were 7 lily pads in a row. 6 frogs sit on 6 lily pads, with an empty one in the middle. The 3 red frogs on the right lily pads want to switch places with the 3 blue frogs on the left lily pads. To do it, they may either: a) hop over one empty lily pad at a time, or b) hop over a frog onto an empty lily pad, like jumping your opponent in the game of checkers. How many moves would it take you to help the frogs switch lily pads? Could you do it in less than 17 moves?
