题目:http://codeforces.com/problemset/problem/732/E 题目大意: 有n台电脑(computer)和m个插座(socket),两者均有一个power值,分别为 ai 和 bi ,只有当两者的power值相等时才可以匹配成功.当然,还有足够多个适配器(adapters)可用,插座每接一个适配器,bi 就会减半(取上整).求最多可匹配多少电脑和插座,以及该种情况下所需要的最少的适配器数量.如有多种方案,输出其中一种即可. 思路: 因为这个题的输出都要用到下…

Java网络编程之TCP ​ TCP主要需要两个类:Socket和ServerSocket,Socket是客户端连接服务器时创建,参数需要指定服务器的ip和端口,ServerSocket是服务器端创建,参数指定端口,如下: Socket socket = new Socket("localhost",8888);//Client.java客户端 ServerSocket serverSocket = new ServerSocket(8888);//Server.java服务器端 //…

第27章 网络通信和系统日志 Sockets and Syslog 基础网络 在本书的前面几章,我们讨论了运转在网络上的服务.其中的两个例子是客户端/服务器架构的数据库和Web服务.当需要制定一个新的协议或者是和一个没有现成库的协议通信时,你就需要使用haskell库中较低级别的网络工具. 在本章中,我们将讨论这些低级的工具.网络通信是整本书都在阐述的广泛的话题.我们将向您展示如何使用Haskell去应用你已经知道的底层的网络知识. Haskell的网络功能几乎总是直接对应于熟悉的C函数调用.由…

http://codeforces.com/contest/732/problem/E 题目说得很清楚,每个电脑去插一个插座,然后要刚好的,电脑的power和sockets的值相同才行. 如果不同,还有一个操作,就是在sockets中插东西,使得sockets的值变成val / 2 + (val & 1) 要求输出最多插多少个电脑和最小的代价. 开始的时候,就有一个暴力的思路了, 就是,用优先队列维护sockets,每次弹出插了最小adapters的一个sockets,然后就是电脑那里找,有得插…
