5.19 - Stacks and Queues

Implement the following operations of a stack using queues. push(x) -- Push element x onto stack. pop() -- Removes the element on top of the stack. top() -- Get the top element. empty() -- Return whether the stack is empty. Notes: You must use only s

说明:这道题初读有点绕....开始我以为只是将一个序列的最大值放到最右边,把最小值放到最左边...所以就怎么也通不过啦.后来终于理解题意了,其实就是要你排个序,从左到右为从大到小.但是改变序列顺序的规则有些特殊,即只能将从最左边开始到某一位置构成的连续子序列进行对称翻转.如有序列:  2,4,9,5,7,6.我选择的位置是5所在的位置,翻转后序列就变为5,9,4,2,7,6.然后用类似于冒泡排序的方法.通过最多两次翻转可以得到最大值,然后放到右边.不断重复上述操作,即可得到一个有序序列. 题目:
