"with index of array as my key" is either redundant -- indicating that 
your answer to my question about "e" should have included something like 
"e is an integer that can range from blah0 to blah_max" -- or not 
understandable.

In any case, seeing that the code in question is only a few lines, why 
don't *you* write an alternative version and see how fast it runs? And 
let us know?
