最近迈克忙着考前复习,他希望通过出门浮躁来冷静一下.迈克所在的城市包含N个可以浮躁的地方,分别编号为1..N.通常迈克在家也很浮躁,所以说他家属于可以浮躁的地方并且编号为1.迈克从家出发,去一些可以浮躁的地方.迈克从第i个可以浮躁的地方到第j个可以浮躁的地方需要消耗abs(i-j)点精力.迈克花费的精力点数是这样算的,比如他去一组地方p1=1,p2,...,pk就需要点精力.当然,如果木有捷径的话走路会很无聊.无论两个地方相隔多远,走捷径的话迈克都只需要消耗1点精力.迈克所在的城市里由N条捷径.…

A.迈克和手机 当迈克在沙滩上游泳的时候,他意外的把他的手机扔进了水里.不过你甭担心因为他立马买了个便宜些的代替品,这个代替品是老款九键键盘,这个键盘只有十个等大的数字按键,按以下方式排列: 1 2 3 4 5 6 7 8 9 0 和他的老手机一起,他存在手机里的电话号码也都丢了.不过由于经常按,他能记住他输手机号的时候手指移动的路径.我们可以把他手指移动的路径看做一组连续的向量(就是可平移的那种),比如手指从5移动到8再移动到6,此时手指的动作和从2移动到5再移动到3是一样的.输入:第一行:一…

The outer world you see is a reflection of your inner self. 你拥有什么样的内心,你就会看到什么样的世界. And we eventually become what we think about. But actually, what we think or what we believe may be of little impacts on the final consequences. What really matters ma…

I only wish to face the sea, with spring flowers blossoming. 我只愿面朝大海,春暖花开. That scenery is beautiful, but it is not exact the life I want. What I want to live is life that I can bring some benefits to those around me, to the group I belong to, to the…

Diligence is the mother of good fortune. 勤勉是好运之母. The mother of good fortune can be diligence, continuous trials and unremitting efforts. But who is the father of good fortune? Maybe the right direction you have chosen. Sometimes if you are in the wr…

It is not the mountain we conquer, but ourselvess. 我们征服的不是高山,而是我们自己. Difficulties and obstacles, just like the mountains in the world, need to be conquered. And more often, they are not so unsurmountable as they look like. As a matter of fact, we can…

这是一道标准的模板题,所以拿来作为这一段时间学习最短路的总结题目. 题意很简单: 有多组输入数据,每组的第一行为两个整数n, m.表示共有n个节点,m条边. 接下来有m行,每行三个整数a, b, c.表示从a到b或从b到a长度为c. 求从1到n的最短路. 先说Floyd—— 这个算法看上去就是一个三重for循环,然后在循环里不断对选择的两个节点进行松弛(感觉松弛这两个字很高端有没有). 算法时间复杂度为O(n^3),n为节点数.所以一般可以用来处理规模1000以下的数据(即100数量级的,但是如…
