help with a regexby jms53 (Monk)
|on Feb 01, 2013 at 18:05 UTC||Need Help??|
jms53 has asked for the
wisdom of the Perl Monks concerning the following question:
I'm trying to understand what the following regex does,
$temp is a string, $temp1 is the same string but entirely lowercase, and %words is populated (word => 1, word2 => 1, word3 =>1 ...).
Where @line contains all the words in a line of input.
