对I/O系统的死锁资源的问题的解决主要的方法是银行家算法，单种资源的银行家算法和多种资源的银行家算法的解决思路一致，要求设计实现多种银行家算法，并要求所涉及的模型最少更够满足如下要求：

(1)程序能够根据进程的请求进行判断，给出系统是否安全的的提示，如果安全，要求能够显示一组进程执行的安全序列；

(2)能够根据需要，显示当前系统中各种资源的分配情况；-The problem I/O system deadlock resources to solve the main method is a banker algorithm consistent single banker algorithm of resources and a variety of resources bankers algorithm to solve the ideas, designed to achieve a variety bankers algorithm, and require the model involved more enough to meet the following minimum requirements:

(1) The program can be judged according to the requesting process, prompting system is safe, and if safety, security sequence requires the ability to display a set of processes　d

(2) can be required to display the current system of allocation of resources
