4月16日,日本熊本地区强震后,受灾严重的阿苏市一养猪场倒塌,幸运的是,猪圈里很多头猪依然坚强存活.当地15名消防员耗时一天解救围困的“猪坚强”.不过与在废墟中靠吃木炭饮雨水存活36天的中国汶川“猪坚强”相比,熊本的猪可没那么幸运,因为它们最终还是没能逃过被送往屠宰场的命运.   我们假设“猪坚强”被困在一个N*M的废墟中,其中“@”表示“猪坚强”的位置,“.”表示可以直接通过的空地,“#”表示不能拆毁的障碍物,“*”表示可以拆毁的障碍物,那么请问消防员至少要拆毁多少个障碍物,才能从废墟中救出“…

ACM小组的Samsara和Staginner对中国象棋特别感兴趣,尤其对马(可能是因为这个棋子的走法比较多吧)的使用进行深入研究.今天他们又在 构思一个古怪的棋局:假如Samsara只有一个马了,而Staginner又只剩下一个将,两个棋子都在棋盘的一边,马不能出这一半棋盘的范围,另外这 一半棋盘的大小很奇特(n行m列).Samsara想知道他的马最少需要跳几次才能吃掉Staginner的将(我们假定其不会移动).当然这个光荣的任 务就落在了会编程的你的身上了. Input 每组数据一行,分别…
