题目分析: 本题我第一次尝试去做的时候用的是优先队列,但是效率不仅代码量很大,而且还有测试样例过不去,很显然没有找到一个好的数据结构来解决这道题目(随着逐渐的刷PAT甲级的题会发现有时选择一个好的解题方向真的比一些花里胡哨的技巧重要的多),对于本题,我们需要模拟的是一个去银行接受服务的过程,银行有k个窗口,而在8点开门之前所有到达的人都在门外排队(在8点后到达的人如果有人则需要排队,窗口中有空位则会选择最空闲的进行自己的服务),首先我们需要对n个用户按照到达的时间进行排序,然后建立一个windo…

题意: 输入两个正整数N,K(N<=10000,k<=100)分别表示用户的数量以及银行柜台的数量,接下来N行输入一个字符串(格式为HH:MM:SS)和一个正整数,分别表示一位用户到达银行的时间以及该用户占用银行资源的时间,求用户的平均等待时间.(当一位用户早于早晨八点到达银行不开门,他需要等待,当一位用户晚于下午五点到达银行关门,该用户不计入等待时间计算)[答案保留一位小数] AAAAAccepted code: #include<bits/stdc++.h> using nam…

有n个客户和k个窗口,给出n个客户的到达时间和需要的时长有空闲的窗口就去办理,没有的话就需要等待,求客户的平均时长.如果在8点前来的,就需要等到8点.如果17点以后来的,则不会被服务,无需考虑. 按客户的到达时间排序建立一个优先级队列,一开始放入k个窗口,初始结束时间为8*3600然后for循环客户,每次从优先级队列中取出最早结束时间的窗口如果客户比结束时间来的早,就需要等待如果客户比结束时间来的晚,就无需等待最后只要统计那些到达时间在17*3600之前的客户即可. #include <iost…

题意:银行有K个窗口用于服务,给出所有人的达到时间T和服务时间P,计算所有被服务的客户的平均等待时间.任何客户的服务时间不得超过60分钟.早于08:00到的,要等到08:00:在17:00:01及之后到的,不给予服务,不参与计算平均等待时间. 思路:首先,对所有顾客的到达时间进行排序:其次,令数组windows[i]表示窗口i当前顾客的结束服务的时间,初始化为08:00,这样的话,每次要安排下一个顾客前往某窗口接受服务时,就遍历所有窗口,找出当前最快结束的那个窗口(记为minidx),然后让这位…
