Anyone have any bright ideas and/or tools to speed up identification of dup
text items in a large list (~30,000)?
The brute-force approach is, of course, to sort the list (which I'm doing using
Shane Stanley's great BridgePlus ASObjC lib), and then just step through the
list comparing one item with the next (is Item i = Item i+1 ?). They are all
text items, could be up to a 100 or so characters. I am expecting that there
is only one dup (two items).
All suggestions appreciated.
Best Regards,
