Unnecessary Shell Calls

Complaining that the cmp is too slow is like complaining that a ten-cent candy bar is too expensive
Maybe the candy should cost only half as much
But it's only five cents, so who cares?
This is another reason not to bother about micro-optimizations
I could probably have sped up the cmp thing by 50% if I worked hard
That would have saved me 2 seconds per run
