Algorithm idea: 1. If there is only a gold film, while the gold from the source to the target mobile wand, The End. 2. If there are n gold films, while the former n-1 gold piece to move to the auxiliary rod, and then move to the goal of their own stick, then the last n-1 before moving to the target rod. 3. Simply to have N a gold piece to move step calculated, you can use recursive methods to meet the recursive equation f (i) = f (i- 1)* 2+ 1
