题意:一个300列的无限行的循环场地,a b d代表a,b顺时针相距d的距离,现在给你一些距离,判断是否有冲突,如果有冲突计算冲突的次数 思路:带权并查集 a,b的距离等于b到根节点的距离 - a到根节点的距离 1.当a,b在同一集合的时候就用b到根节点的距离 - a到根节点的距离和当前输入的距离进行对比,看是否满足条件 2.当a,b不在同一集合的时候合并两个节点,更新距离 向量法,方向一定要搞清楚,父亲指向儿子 如果x的父亲rootx ,y的父亲是rooty rootx --> x, root…

题意:浙江省第十二届大学生运动会在浙江师范大学举行,为此在浙师大建造了一座能容纳近万人的新体育场. 观众席每一行构成一个圆形,每个圆形由300个座位组成,对300个座位按照顺时针编号1到300,且可以认为有无数多行.现在比赛的组织者希望观众进入场地的顺序可以更加的有趣,在门票上并没有规定每个人的座位,而是与这个圈中某个人的相对位置,可以坐在任意一行. 门票上标示的形式如下:A B x 表示第B个人必须在A的顺时针方向x个位置(比如A坐在4号位子,x=2,则B必须坐在6号位子). 现在你就座位志愿…

<题目链接> <转载于 >>> > 题目大意: 有n个人坐在zjnu体育馆里面,然后给出m个他们之间的距离, A B X, 代表B的座位比A多X. 然后求出这m个关系之间有多少个错误,所谓错误就是当前这个关系与之前的有冲突. 解题分析: (1)弄清题意,找出出现冲突的位置,判断冲突很简单就是当两个人在同一行坐,同时他们到根节点的距离差值正好是他们之间的差值,此时就出现了冲突了. (2)关键有两个地方,这也是并查集题目的难点,就是压缩集合,和求节点到根的距离.这里压…
