目的与要求：

本设计的目的是通过对死锁检测算法的模拟，来了解死锁检测中的数据结构的设计和使用以及资源分配图在死锁检测中的应用。具体要求如下：

⑴模拟一个死锁检测算法；

⑵该算法能通过简化资源分配图来检测死锁；

⑶资源分配图可以用矩阵的形式表示；

⑷输出结果为有死锁或无死锁。

-Purpose and requirements: The purpose of this design is the deadlock detection algorithm through the simulation, to understand the deadlock detection data structure, as well as the design and use of the resource allocation map in the deadlock detection. Specific requirements are as follows: ⑴ simulated a deadlock detection algorithm　⑵ The algorithm can simplify the allocation of resources to detect the deadlock graph　⑶ resource allocation plan can be expressed in the form of matrix　⑷ output for the deadlock or deadlock-free.
