No!

No downvote, but your regex misses the limit of 1 to 4 "f"s in OP's statement of the problem.

See FunkyMonk's prior reply (which <span class="pedantic picky)"> errs (albeit, in it's original form, and only marginally) in the comment at line 4:

{1,4} # between 1 & 4 of them

only insomuch as the set of integers between "1 & 4" includes only "2" and "3."</span>

Hmm... :-) maybe the "picky pedantic" tag should enclose this whole note....

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


Do you know where your variables are?
