LittleJohn (我行故我) 于 h 提到:
There are 25 horses and only five tracks in a race (i.e., you can race 5
horses at a time). There is no stop clock !! Assume that there are no ties.
Question: What is the minimum number of races needed to
rank all the 25 horses ?
What I can think of now is to write a program to simulate it, but haven't
found an efficient way of doing it.
Appreciate if someone can give any hint.
