| Place a half dollar in the first box from the left, a quarter in the second, a dime in the third, a nickel in the fourth, and a penny in the fifth. The final two boxes are left empty, so you get (h)(q)(d)(n)(p)( )( ) (see top drawing). Now reverse the order of the coins in seven moves to become (p)(n)(d)(q)(h)( )( ) as shown in the bottom drawing. Each move consists of moving two adjacent coins to the two empty boxes. Don't switch the left-right ordering of the coins when you move them. | ||||||||||||||||||
