1682. Crazy Professor(并查集)】的更多相关文章

1628 加了些数论知识  先看下剩余类的概念 一个整数被正整数n除后,余数有n种情形:0,1,2,3,…,n-1,它们彼此对模n不同余.这表明,每个整数恰与这n个整数中某一个对模n同余.这样一来,按模n是否同余对整数集进行分类,可以将整数集分成n个两两不相交的子集.我们把(所有)对模n同余的整数构成的一个集合叫做模n的一个剩余类. 对于a%k=x b%k=y  若x!=y  a与b有边相连 则a的剩余类  与b的剩余类l里的元素也是可以相连的  即 a ->b->a+k->b+k-&g…
[题目链接] http://acm.timus.ru/problem.aspx?space=1&num=1682 [题目大意] 给出k,从1开始不断地加一并把这个数写在黑板上,如果写上的数字和之前的数字满足 (a+b*b)%k=0或者(b+a*a)%k=0就在他们之间连一条线,如果黑板上出现环就结束,问能写几个数 [题解] 我们发现写到2k-1的时候,就一定会产生一个环,所以我们只要枚举数字 往满足要求的地方连边,判断是否出现环即可 [代码] #include <cstdio> #in…

题目描述 S 城现有两座监狱,一共关押着N 名罪犯,编号分别为1~N.他们之间的关系自然也极不和谐.很多罪犯之间甚至积怨已久,如果客观条件具备则随时可能爆发冲突.我们用"怨气值"(一个正整数值)来表示某两名罪犯之间的仇恨程度,怨气值越大,则这两名罪犯之间的积怨越多.如果两名怨气值为c 的罪犯被关押在同一监狱,他们俩之间会发生摩擦,并造成影响力为c 的冲突事件. 每年年末,警察局会将本年内监狱中的所有冲突事件按影响力从大到小排成一个列表,然后上报到S 城Z 市长那里.公务繁忙的Z 市长只…
