摘要

图1表示一个有三部电梯的八层建筑。阴影的单元格代表特定电梯呼叫的楼层。请注意，所有的电梯都在顶层和底层，以及中间的四层。在这种结构下，乘坐一部电梯在任意两层楼之间穿梭是可能的。问题是，如果每台电梯在顶层和底层之间的三层召唤，需要多少部电梯才能使任意两层楼由一台电梯连接?

A Tokyo Elevator Puzzle

Figure 1 represents an eight-storey building with three elevators. The shaded cells represent those floors at which a particular elevator calls. Notice that all elevators call at both top and bottom floors and four floors in between. It is possible, given this configuration, to travel between any two floors by riding a single elevator. The question is, if each lift called at three floors in between top and bottom, how many lifts would be required such that any two floors are connected by a single elevator?
