说明：  银行家算法是一个避免死锁的著名算法，是由艾兹格·迪杰斯特拉设计的一种避免死锁产生的算法。它以银行借贷系统的分配策略为基础，判断并保证系统的安全运行。
(Banker algorithm is a well-known algorithm to avoid deadlock. It is a algorithm designed by Azeg Dijkstra to avoid deadlock. It is based on the allocation strategy of bank lending system, and it determines and ensures the safe operation of the system.)
