http://poj.org/problem?id=2236 由于发生了地震,有关组织组把一圈电脑一个无线网,但是由于余震的破坏,所有的电脑都被损坏,随着电脑一个个被修好,无线网也逐步恢复工作,但是由于硬件的限制,一台电脑和另一台电脑能够相连当他们之间的距离小于d,或者还有一台电脑当中介,分别与两台电脑相连. 在修复的过程中,工作者会有两种操作,修复电脑和询问电脑a和电脑b是否相连.当询问的时候输出答案. 因为输入数据很大,需要快速判断电脑a和电脑b相连,所以自然想到用并查集. 初始时候 全部电…

题目地址:http://poj.org/problem?id=2236 题目大意:n台电脑都坏了,只有距离小于d且被修好的电脑才可以互相联系,联系可传递.输入n和d,n个点的坐标x y.两个操作:O x表示把电脑x修好了,S x y表示询问x和y能否联系. 思路:并查集把能互相联系的电脑都放到同一个集合里(联系可以互相传递),查询的时候只要看x和y是否在一个集合就行了. 另设置两个数组visit[x]表示x是否被修好,dis[x][y]表示x和y之间的距离是否符合要求[先预处理任意两个点之间的距…
