看题:传送门 大意就是让你编写一个称为argus的系统,这个系统支持一个register的命令: Register  Q_num Period 该命令注册了一个触发器,它每Period秒就会残生一个编号为 Q_num的事件.你的任务就是模拟出前k个事件.如果多个事情同时发生,先处理Q_num小的事件. 优先队列的使用. 练习了用struct类自定义优先级. #include<iostream> #include<cstring> #include<cstdio> #in…

UVAlive 3135 Argus Argus Time Limit: 3000MS   Memory Limit: Unknown   64bit IO Format: %lld & %llu Submit Status Description A data stream is a real-time, continuous, ordered sequence of items. Some examples include sensor data, Internet traffic, fin…

将多个有序表合并成一个有序表就是多路归并问题,可用优先队列来解决. #include <cstdio> #include <queue> using namespace std; + ; struct Node { int time, period, num; bool operator < (const Node& rhs) const { return time > rhs.time || (time == rhs.time && num &…

A data stream is a real-time, continuous, ordered sequence of items. Some examples include sensor data, Internet traffic, financial tickers, on-line auctions, and transaction logs such as Web usage logs and telephone call records. Likewise, queries o…

https://vjudge.net/problem/UVALive-3135 题意: 有一个系统有多个指令,每个指令产生一个编号为qnum的时间,每个指令的触发间隔不相同,现在给出若干个指令,现在的任务是模拟前k个事件. 如果时间在同一时间发生,那么qnum小的先输出. 思路: 很多相同的数值在同一时刻内,数值小的先输出,那么就是求若干个中最小的,那么就可以用优先队列进行维护. 这里,因为时间范围较小,之后每个事件的时间取余,那么符合的就把一个结构体扔进优先队列,这个结构体包括了qnum,pe…

题目大意:有若干命令,它有两个属性Q_Num,Period(周期).按时间循序模拟前k个命令并输出他们的Q_Num,若同时发生输出Q_Num最小的值. #include<iostream> #include<cstdio> #include<cstring> #include<queue> using namespace std; struct Item { int QNum,Period,Time; bool operator < (const It…
