题A: 一共有25匹马,有一个赛场,赛场有5个赛道,就是说最多同时可以有5匹马一起
比赛。假设每匹马都跑的很稳定,不用任何其他工具,只通过马与马之间的比赛,试问
,最少得比多少场才能知道跑得最快的5匹马?
题B: 49 匹赛马. Assume for each one, it travels the track in the same
amount of time every time. Also assume no two finish the track in the same
amount of time. Suppose you have 7 tracks, but no timer. Design races to
find the 25-th fastest with minimal number of races
记得好像板上讨论过,找不到了原帖。 不知道有什么好的系统的解法。
