in thread LCCS time complexity

Thanks for the   $text =~ s/\[[^\]]*\]/ /g; tip; that is better. As for the  /m on these
$text =~ s/^\s+//; $text =~ s/\s+$//;
I think I'd put the  /m on the third RE
$text =~ s/\s+/ /m; #yes?
so taken together the triple REs mean: "remove leading whitespace, trailing whitespace, and make all interior whitespace (even across line breaks) into single spaces".

Many thanks for the OT-but-useful teaching!

    The /m only modifies the match behaviour of ^ and $ letting them match the begining and end of any line rather than entire string. It has no effect on the final RE which just needs a /g to do all interior whitespace.

    cheers
