Well, I didn't propose it.  I don't know what the guy who suggested it
had in mind, one way or the other.

I initially thought it would be a hard problem (or at least take a
long time to solve), thus my cautionary remarks, but the solution
posted here earlier took ~0.001 seconds on my machine.  I guess this
dataset was sufficiently small.  :)
