一直以来我就好奇,为什么希腊的中文名字“希腊”和英文名字”Greece”听起来都不像(就像“德国”不像“Germany”一样),而且,为什么在很多体育比赛中看到希腊运动员的衣服上都是“Hellas”,而不是“Greece”. 昨天,我终于弄明白了. 这还要感谢相公的同事Sotiris.我在FaceBook上看到他加入了一个组,叫“The name is Hellas, not Greece”,于是问他背后有什么故事,他跟我在FaceBook上婉婉道来. 先说Hellas.希腊人从来都叫希腊作”H…

2015-06-05 问题简述: 有一个 p*q 的棋盘,一个骑士(就是中国象棋里的马)想要走完所有的格子,棋盘横向是 A...Z(其中A开始 p 个),纵向是 1...q. 原题链接:http://acm.tju.edu.cn/toj/showp1702.html 解题思路: DFS:深搜把所有情况都考虑一遍,当骑士走出棋盘或走到原来走过的格子时,旅行失败了:当骑士能一直走下去直到走过的格子数等于 p*q 时,旅行成功. 提交过程中一直有一个问题使这个代码一直WA,最后才发现是 p.q输入反了…

cf788B/789D. Weird journey 题意 n个点m条边无重边有自环无向图,问有多少种路径可以经过m-2条边两次,其它两条边1次.边集不同的路径就是不同的. 题解 将所有非自环的边变成两份.然后去掉两条边,看有没有欧拉路. 如果两条边都不是自环,那么只当他们相邻时(共享一个点),剩下的图有两个奇数度的点.有欧拉路.所以第i个点作为共享的点,有\(C(cnt_i,2)\)种路径. 如果其中一个是自环,那么其他m-1条边任意选一个都可以.有loop*(m-1)条,不过每个自环算了两次…
