in reply to Re^3: regex, find words that occur more than once.
in thread regex, find words that occur more than once.
*ugh* Never mind the below as I forgot completely that regex was already accounting for the repeated words.
words that occur more than once
So without a counter as you state ...
... For purposes of answering the question "Has this word repeated" $words{$1} = undef; works just as well and the following increment is not required.
... I fail to see how one can find if a word appears more than once. The best one could know is if a word appears at all.
