     1) The streams-based solution is gazillions of times slower
than your basic loop.

     2) Your basic loop is gazillions of times faster than ...
a correct solution.  (Ponder this a while.)

     3) This is not the first "efficiency" question you've asked, which
leads me to fear that you may be well on the way to becoming an addict.
Stop!  Stop now, while you still can!  "Efficiency" is a drug as habit-
forming and as destructive as anything you can find in a darkened back
alley.  If you get hooked, you'll never get clean.  Trust me, I know:
The monkey has ridden my back for half a century despite my strenuous
efforts to dislodge it.  Don't follow my pathway to ruin!
