用银行家算法设计一个程序，判断当前资源分配状态是不是安全状态；如果是安全状态，当系统接收新的资源申请时，系统是否发生死锁，如发生，请找出参与死锁的进程。如果不发生死锁，则找出一组能够顺利推进的进程顺序。(Bankers algorithm design a program to use to judge the current state of resource allocation state is safe; If it is a safe state, when the system is receiving new resources application, system if a deadlock occurs, such as, please find the process involved in a deadlock. If not a deadlock occurs, is to find a group would be able to promote the process of order.)
