The simplest optimization would be to create the 'sb' buffer
at least as big as the 'input' string. After all, even if
there were no actual substitutions, the 'sb' would be as big,
and this would avoid StringBuffer doing a lot of
reallocations, especially if 'input' is more than the 16
Try it simpler:
Yes, that's much nicer. See what happens when I tried to fit a solution in
to the previous coding paradigm? wink This was better refactored and it
certainly does the job much nicer. The only change I'd make is to make the
StringBuffer size length+5 to ensure we can at least
