1.1 作业描述某停车场共有TOTAL-NUM个车位,ENTRY-NUM个进口,EXIT-NUM个出口.现需要一个用于停车场控制汽车进出的分布式系统,在该系统中没有集中的管理者(centralserver),每个进(出)口通过通信平等协商保存当前车库的状态信息(如空闲车位数UNOCCUPIED-NUM等),并据此决定是否允许车辆进入,为简便计,假定通信是可靠的.1.2 作业要求1) 不考虑节点/进程失效的情形,设计用于该停车场控制的分布式系统,并给出汽车进出时使用该系统的方法.2) 证明你所设计的分布式系统中使用的同步算法满足ME1-ME3*.3) 如果新增一个进口节点/进程,请考虑如何使该进口能参与工作.

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
