Problem Description“连连看”相信很多人都玩过。没玩过也没关系，下面我给大家介绍一下游戏规则：在一个棋盘中，放了很多的棋子。如果某两个相同的棋子，可以通过一条线连起来（这条线不能经过其它棋子），而且线的转折次数不超过两次，那么这两个棋子就可以在棋盘上消去。不好意思，由于我以前没有玩过连连看，咨询了同学的意见，连线不能从外面绕过去的，但事实上这是错的。现在已经酿成大祸，就只能将错就错了，连线不能从外围绕过。玩家鼠标先后点击两块棋子，试图将他们消去，然后游戏的后台判断这两个方格能不能消去。现在你的任务就是写这个后台程序。Input输入数据有多组。每组数据的第一行有两个正整数n,m 阅读全文

Problem Description前文再续，书接上一题。话说当上小面的司机的Lele在施行他的那一套拉客法则以后，由于走的路线太长，油费又贵，不久便亏本了。(真可怜～)于是他又想了一个拉客的办法。对于每一次拉客活动，他一次性把乘客都拉上车(当然也不会超过7个，因为位置只有7个)。然后，Lele计算出一条路线(出于某些目的，Lele只把车上乘客的目的地作为这条路线上的站点），把所有乘客都送到目的地(在这路线上不拉上其他乘客)，并且使总路线长度最短。不过Lele每次都要花很多时间来想路线，你能写个程序帮他嘛？ Input本题目包含多组测试。最后一组测试后有一个0代表结束。每组测试第一行有一个整 阅读全文
