Description: 1．密码锁有两个密码：一是设计密码，放存在ROM中；另一个是使用密码，存于EEPROM中。
2．.密码锁的密码用4位有效数字，输入超过4位时以最后输入4位数字为准，数字范围由1~6。
3. 用实验板上K1—K6键作密码数字输入键，分别表示1~6数字，K7，K8键为命令键。其中，K7为密码设置键，K8为开锁键。蜂鸣器用作开锁指示。
4. 开机后进入初始状态，显示器显示“— — — —” 且最高一位闪动，闪动位亦表示当前数字输入位，以后每输入一位数字，闪动位向右循环移动。
5．开锁功能：在初始状态下，从K1—K6键输入密码，再按K8键。
若输入密码的最后4位数与存EEPROM的使用密码内容相同或与存于ROM中的设计密码相同，则开锁成功，并用蜂码器发声指示。 否则输入错误返回初始状态。
开锁状态维持 60秒，超过时间，则自动关闭开锁状态，同时停止声音输出。
6.修改密码功能，在开锁状态下，用K1~K6键输入4位新的使用密码，若超过4位数则以最后4位数为准，然后按K7键，则完成密码修改。新密码存到 EEPROM中，覆盖原来的使用密码，且新密码闪动三下，表示修改成功。完成后自动回到初始状态。 若不在开锁状态或在开锁状态下数字键输入不足4位，按K7键就无效，返回初始状态。
-1. There are two locks Password: First, the design of the password, put there in the ROM another is to use the password in stored in EEPROM.
2. . Cipher-lock with the password 4 digits, enter more than four hours to enter the last four figures, the figures range from 1 ~ 6.
3. With the experiment on-board keys K1-K6 password for digital input keys, respectively, 1 ~ 6 figures, K7, K8 key for command button. Which, K7 keys for password setting, K8 for the unlock key. Unlock instructions for the buzzer.
4. Boot into the initial state, the display shows "----" and a maximum of a flashing, flashing-bit digital input also said that the current place for every subsequent importation of a number of mobile flashing circle to the right place.
5. Unlock feature: in the initial state, K1-K6 keys from a password, and then key K8.

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
★ experimental tasks
Millet finally came to the school, I am glad that he left him to solve the problem of seniors, has been appreciated by seniors. He played
Point luggage went back to the bedroom, only to find the entrance to the dormitory where the door is not actually opened with a key, just wonder millet
To wonder, how did not send the key, after millet careful "research", and finally found this to be a lock.
This lock is very strange, the password prompt is a string of 1 to n, arranged, he found that this sequence has a rule: If
i there, then the subsequent number smaller than i are in descending order. That this was what, millet understood why. Only the door
Two buttons and a vertical slot, one PUSH key, another POP key. Fall from the top of each tank system, a digital card
Pieces (from 1 to n), PUSH representative to the number in temporary tanks (after first-out), POP out on behalf of a number from the temporary tank

Description: 数据结构实验报告
实验1 线性表及其应用
题目：约瑟夫环
一． 需求分析
1． 本演示程序中，人数n应为任意的，首先应输入一个值赋给初始报数上限m，程序应能自动保存出列人的序号和将出列的人所持的密码赋给m，再次作为报数上限，如此循环，直至所有人都出列为止。
2． 演示程序以用户和计算机的对话方式执行，即在计算机终端上显示“提示信息”之后，由用户在键盘上输入相应数据（即每个人所持的密码），每个人的序号由程序自动分配。
3． 程序执行的命令包括：
（1）构造链表；（2）输入数据；（3）执行报数，储存出列人的序号，删除出列人的信息以及把出列人的密码赋给m；（4）结束。
4． 测试数据
（1）n＝7，7个人的密码依次为：3，1，7，2，4，8，4，首先m值为6，则这正确的出列顺序为6，1，4，7，2，3，5。

（2）针对DES密钥特点（8字节，64比特位，其中真正起作用的为56比特位），设计一次一密的密钥产生机制（即每次会话所使用的密钥都是临时随机产生的）；
2、非对称密码技术的实现
（1）熟悉RSA相关函数（公私钥生成函数，加密/解密函数）；
（2）利用公钥加密特定文件（test-1.txt），并用私钥进行解密；反过来，再利用私钥加密特定文件，并用公钥进行解密。对比解密后的文件与原始文件是否一致。
3、信息摘要技术的实现
（1）熟悉MD5算法的实现函数；
（2）利用MD5实现函数，对特定文件（test-1.txt）进行信息摘要的计算，得到信息摘要M1；尝试改变特定文件中的内容（比如改变其中某个字母），再利用MD5计算一次信息摘要，看同之前得到的信息摘要是否相同；
设计要求
