说明：  银行家算法是由Dijkstra设计的最具有代表性的避免死锁的算法。本实验要求用高级语言编写一个银行家的模拟算法。通过本实验可以对预防死锁和银行家算法有更深刻的认识。
(Banker's algorithm is the most typical deadlock avoidance algorithm designed by Dijkstra. This experiment requires the use of high-level language to write a banker's simulation algorithm. Through this experiment, we can have a better understanding of deadlock prevention and banker's algorithm.)
