More as a general point about this class of problem, it's my turn to repeat the well-worn advice about "whenever you start finding yourself with variables ending with incremental numbers, it's time to use arrays instead."

There's nothing at all wrong with assigning an array to a grep'ed version of itself, any more than there is map'ing one - you really don't need @cards1, @cards2 etc.

As Zaxo said, shuffling and popping would be better here, but should you wish to do this (or similar) "in place" as you are doing, something like this would be easier...

while (@hand < $num_to_deal) { return "no more cards" unless @cards; push @hand,$cards[int(rand(@cards))]; @cards = grep{$_ ne $hand[$#hand]}@cards; }
NB - I'm not advocating this code - as others have said, the grep is nasty - just pointing out a principle :)

Cheers, Ben.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
