Description: 密码
★实验任务
小米终于来到了学校，很高兴，他解决了学长留给他的问题，得到了学长的赞赏。他打
点行李回寝室去了，到了宿舍门口才发现这里的门居然不是用钥匙开的，怪不得刚才小米
就觉得奇怪，怎么没有发钥匙，经过小米的仔细“研究”，终于发现这是个密码锁。
这个密码锁很奇怪，密码提示是一串 1 到 n 的排列，他发现这个序列有一个规律：如果
i 出现，那么其后出现的小于 i 的数均为降序。原来是这么回事，小米恍然大悟。门上只有
两个按键和一个竖槽，一个是 PUSH 键，另一个 POP 键。系统每次从槽顶掉入一个数字卡
片（从 1 到 n），PUSH 代表把该数放入暂存槽（后入先出），POP 代表从暂存槽取出一个数
作为当前你要输入的密码。如下图所示：
众所周知，小米很懒，每次进门都要算，多麻烦啊，于是他就找你帮忙，给你一串序
列，其值为 1 到 n 的一个排列，输出形成该序列的操作。
★数据输入
输入首先为n（1<=n<=20000），接下去为1到n的一个排列。
★数据输出
输出形成该序列的操作，数据保证该序列可以形成。-Password

i there, then the subsequent number smaller than i are in descending order. That this was what, millet understood why. Only the door
