这题写了有一点时间,最开始想着优化一下时间,用优先队列去做,但是发现有锅,因为忽略了队的长度. 然后思考过后,觉得用时间线来模拟最好做,先把窗口前的队列填满,这样保证了队列的长度是统一的,这样的话如果到某个时间,队首的人已经服务完了,这样这个队列的长度就减少一,这就变成了所有队列中长度最短的队列,所以直接向这个队列里面添加一个人就可以了. 按照从小到大轮询窗口的话,这样正好符合题中的要求,就是队列长度相同短,先选窗口序号小的窗口.如果按照这种策略,少一个就补一个的策略,队列长度会一直保持相等.…

题面: 输入四个正整数N,M,K,Q(N<=20,M<=10,K,Q<=1000),N为银行窗口数量,M为黄线内最大人数,K为需要服务的人数,Q为查询次数.输入K个正整数,分别代表每位顾客需要被服务的时间,Q次查询每次查询一位顾客被服务完离开银行的时间.如果他在五点以前(不包括五点)没有开始被服务,输出“Sorry”. trick: 在五点以前(不包括五点)没有开始被服务,输出“Sorry”,而不是被服务完时间在五点以后(以题面为准). AAAAAccepted code: #inclu…
