Problem posed to me by Ankit Goyal (Civil, H2)
There are 25 horses. You want to find the best 3. Of course having a race and finding the top 3 is easy, but the constraint is that only 5 horses are allowed to race at once. Find the top 3 horses having minimum number of races.
Post your answer here. The first to reply with a correct answer (except Ankit) gets an H8 canteen treat!!!
