描述 n台电脑,如果两台电脑间的距离的d范围内,则两台电脑能够连通. 如果AB连通,BC连通,则认为AC连通. 已知电脑台数N,最大距离d,以及每个电脑的坐标.有如下两种操作: O i 表示修复编号为i的电脑 S i j 表示判断电脑ij能否连通. 对每一个S操作,如果电脑ij能连通,输出SUCCESS,否则输出FAIL 思路 典型的并查集. 初始:每个点的父节点都是自身   每修复一个点,让所有能与这个点连通的点的根节点都指向这个点的根节点 每查询两个点,取得它们的根节点,判断是否相同,如果相…

Wireless Network 这接翻译了 Descriptions 地震发生在东南亚.ACM(亚洲合作医疗团队)已经与膝上电脑建立了无线网络,但是一次意外的余震袭击,网络中的所有计算机都被打破了.计算机一个接一个地修复,网络逐渐开始工作.由于硬件限制,每台计算机只能直接与距离它不远的计算机进行通信.但是,每台计算机都可以被视为两台其他计算机之间通信的中介,也就是说,如果计算机A和计算机B可以直接通信,或者计算机C可以与A和A进行通信,则计算机A和计算机B可以进行通信. B. 在修复网络的过程…

http://poj.org/problem?id=1459 题意:有np个发电站,nc个消费者,m条边,边有容量限制,发电站有产能上限,消费者有需求上限问最大流量. 思路:S和发电站相连,边权是产能上限,消费者和T相连,边权是需求上限,边的话就按题意加就好了.难点更觉得在于输入..加个空格..边数组要*2,因为有反向边. #include <cstdio> #include <algorithm> #include <iostream> #include <cs…
