设计程序模拟预防进程死锁的银行家算法的工作过程。假设有系统中有n个进程P1, … ,Pn，有m类可分配的资源R1, … ,Rm，在T0时刻，进程Pi分配到的j类资源为Allocationij个，它还需要j类资源Need ij个，系统目前剩余j类资源Workj个，现采用银行家算法进行进程资源分配预防死锁的发生。-Process simulation program designed to prevent deadlock bankers algorithm works. Suppose the system has n processes P1, ..., Pn, there are m types of resources can be allocated R1, ..., Rm, at the time T0, the process Pi assigned to the j class resources Allocationij one, it requires resources Need class j ij a system is currently remaining resources Workj a class j, is the process of using the banker' s algorithm for the allocation of resources to prevent deadlock from occurring.
