客户业务分2种，第一种是申请从银行得到一笔资金，即借款或取款。第2种是向银行投入一笔资金，即存款或还款。银行有2个服务窗口，相应地有2个队列。客户到达银行后先排第一个队。处理每个客户业务时，如果属于第一种，且申请额超出银行现存资金总额尔得不到要求，则立刻排入第2个队等候，直至满足时才离开银行，否则业务处理完后立刻离开银行。没接待完一个第二种业务的客户，则顺序检查和处理（如果可能）第二个队列中的得客户，对能满足的申请者予以满足，不能满足者重新排到第二个队列的队尾。注意，再此检查过程中，一旦银行资金总额少于或等于刚才第一个队列中最后一个客户（第2中业务）被接待之前的数额，或者本次以将第2个队列检查或者处理了一遍，就停止检查（因为此时已不可能还有满足者）转而继续接待第一个队列的客户。任何时刻都只能开一个窗口。假设检查不需要时间。营业时间结束时所有客户立即离开银行。写一个上述银行业务的事件驱动模拟系统，通过模拟方法求出客户在银行内逗留的平均时间。基本要求： 利用动态存储结构实现模拟。-Client s business is divided into two kinds, the first application to get funds from the bank, that loans or withdrawals.
