首先，这三者都是顺序容器适配器（适配器(adaptor)是根据原始的容器类型所提供的操作，通过定义新的操作接口，来适应基础的容器类型）。本质上，适配器是使一事物的行为类似于另一事物的行为的一种机制。容器适配器让一种已存在的容器类型采用另一种不同的抽象类型的工作方式实现。例如，假设deq是deque类型的容器，则可以用deq初始化一个新的栈：stack stk(deq);//带容器参数的

（PS：可在《算法（第四版）》的1.3.49看到此题）两年前从网上看到一道面试题：用两个栈（Stack）实现一个队列（Queue）。觉得不错，就经常拿来面试，几年下来，做此题的应该有几十人了。通过对面试者的表现和反应，有一些统计和感受，在此做个小结。 用C++描述，题目大致是这样的： 已知下面Stack类及其3个方法Push、Pop和 Count，请用2个Stack实现
