( #3333=superdoc: print w/replies, xml ) Need Help??


my @ips = qw( ); my @sorted = map { $_->[1]; } sort { $a->[0] cmp $b->[0] } map { [ sprintf("%03d.%03d.%03d.%03d", split /\./), $_ ] } @ips; print map { $_.$/ } @sorted;
Is that reasonable? (I did test it - it seems to work for the example above.)

Update: Change the @sorted line to this also works:

my @sorted = map { $_->[1]; } sort { $a->[0] <=> $b->[0] } map { [ sprintf("%03d%03d%03d%03d", split /\./), $_ ] } @ips;

This one uses numerical comparison... not really sure which one would be faster. I like the first one better if only because it looks to me like I'm doing what I say I'm doing, where as this one looks more like I'm faking it.

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 or How to display code and escape characters are good places to start.
