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 &…

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…

https://vjudge.net/problem/UVALive-3135 题意: 你的任务是编写一个称为Argus的系统.该系统支持一个Register的命令 Register Q_num Period 该命令注册了一个触发器,它每Period秒钟就会产生一次编号为Q_num的事件.你的任务是模拟出前k个事件.如果多个事件同时发生,先处理Q_num小的事件. 思路:题目很简单,一个优先队列解决. #include<iostream> #include<cstring> #in…

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…

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…

在网上总是查不到很系统的练ACM需要学习的数据结构资料,于是参考看过的东西,自己整理了一份. 能力有限,欢迎大家指正补充. 分类主要参考<算法竞赛入门经典训练指南>(刘汝佳),山东大学数据结构模板 ⊙基本数据结构 1.链表: 块状链表:没练过 Dancing Links:用于优化搜索.解决精确覆盖问题和重复覆盖问题的利器. Knuth教授的始祖论文:Dancing Links中文版 Dancing Links介绍(这篇对DLX的工作过程演示的很详细) DLX——Dancing Links(这篇…
