返回信息流Write a method areEqual that returns true if the two stacks specified in the parameters have the same elements in the same order, and false otherwise. Two elements are the same if they refer to the same object. The method may remove elements from the stacks, but it must return the elements to the stacks in the same order to restore the stacks to their original state. The only additional data structure that it can use as auxiliary storage is a single stack (i.e., no arrays, no ArrayLists, no linked lists no queues, no strings...). The method may also use O(1) additional space
这是我在写的一个函数，空间复杂度为O(1),我实在想不通怎用固定空间解决
