With an array of that size, is it coming from a file? If so, you can do
something like this to cut down on memory usage, which will speed up the
process. I'm not the expert on regexes, but I believe there is also a way
to have the regex compiled only once.
my $counter;
while(<INFILE>){
$counter++;
if($_ =~ /(\b$input\b)/){
print "Found match on line number $counter\n";
}
}

Hi,
Thanx for ur reply.This is exactly what i am
looking for.But if @rootwords is a huge array of
length 50000(for example),then it would take some time
to find a match.Is there any other way to tackle this?
