I meant in terms of affecting the performance of this function.. We
know the total length of the string, including spaces, coming into the
function. If the updated function is always faster when the overall
string is at least, say, 16 characters long, then Dimitri's suggestion
to just check the overall length coming in and decide which approach to
use might make sense. If the new function is always slower, regardless
of overall string length, when there's only 1 extra space at the end,
then chances are it's not worth it.
Thanks,
