/*
* 算法简述(主要分为如下三个步骤)：
*
* 1、首先将该按钮上面的按钮推上去（相当于点击被“推上去”的这个按钮），在推动的过程中，
* 如果被推动的按钮的上面还有另一个按钮，则重复这个过程(步骤 1)
* 2、然后将自己推上去
* 3、最后将该按钮下面的按钮推下去（相当于点击被“推下去”的这个按钮），在推动的过程中，
* 如果被推动的按钮的上面还有另一个按钮，则重复这个过程(步骤 3)
*
* 整个过程就像你站在队伍中，你想前进，首先你得告诉站在你前面的人前进，然后你必须等待，直到你前面的人
* 前进之后你才能够前进。（你前面的人同样必须和你做同样的事，这个过程直到传达到第一个人为止）
*
*
*
* 还没有明白吗？没关系，我们来举例说明这个算法：
* 为了方便理解程序，我们以“按钮1”、“按钮2”、“按钮3”和“按钮4”这四个从上到下依次排列的按钮为例，
* 我们假设“按钮3”被点击：
* 1、将“按钮1”推到最顶端
* 2、将“按钮2”推到“按钮1”的下方。
* 3、将自己（“按钮3”）推上去；
* 4、将“按钮4”推下去。
*
*
* 本程序中主要运用了属性的特点。
* 因为使用的是中文编程，所以就不再详细说明了。
