so let's arrange our duckies in order of speeds fastest duckyvery fast duckyfast duckyduckduckvery fast duckyfast duckyduckduckduckfast duckyduckduckduckduckduckduckduckduckduckduckduckduckduckduck so fastest ducky is for sure #1 but then there's very fast duckies and fast duckies that we need to race, and they'll be the last race |

--- Quote from: Conan on August 15, 2017, 07:52:01 PM ---but that still doesnt handle the case the top 3 are in the first group whats the 7th race? --- End quote --- so let's say you have this orientation: group A: group B: group C: a0 b0 c0 a1 b1 c1 a2 b2 c2 The groups are sorted in order of a0 > b0 > c0. Since we know a0 is the fastest, we don't need to race it. We race the following ones in bold: group A: group B: group C: a0 b0 c0 a1 b1 c1 a2 b2 c2 there are only limited possibilities here. Valid combinations are: a0 > a1 > (a2 or b0) > etc. a0 > b0 > (a1 or b1 or c0) > etc. Note that c1 isn't even a possibility here, since b0 > c0, the only possibility that includes the c group is a0 > b0 > c0. c1 can't even come into play. The top 2 of this race is the bottom 2 of the top 3 that you originally wanted to get. I'm 90% sure the person who originally posted this got it from a youtube video because I literally just saw it like a day before it was posted here, by the way |
