so let's arrange our duckies in order of speeds

fastest duckyvery fast duckyfast duckyduckduck
very fast duckyfast duckyduckduckduck
fast duckyduckduckduckduck
duckduckduckduckduck
duckduckduckduckduck

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

but that still doesnt handle the case the top 3 are in the first group

whats the 7th race?
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

can we just conclude that ducks are good

was about horses
I may have adapted it so people can't google it lol
I did solve it myself before watching how they went about it

I think I found it after watching some google interviews, which I don't even remember how I got to those
they were rather interesting though, kind of easy coding problems

we watched the same video i guarantee it

maxwell thanks for helping me with my maths equations



nothing but good ol PEMDAS
