The problem with this challenge can be seen in the initial 
comments. Writing the fastest possible program *for a specific 
dataset* is not the same thing as writing the fastest program for 
an arbitrary dataset of that size. And, indeed, the fastest 
program is the one that does nothing but print the answer.

Speed on this task doesn't tell you anything about performance 
with different types/sizes of data or constraints on programmer 
time needed to produce a correct implementation and maintain it 
over time.
