Well, still using map, this seems a good candidate for Guttman-Rossler, and such an approach is also compatible with jesuashok's new requirement:
#!/usr/bin/perl -l use strict; use warnings; my @data=qw/1-1 6 2-5 1-10 7 1-3 2-1/; print for map +(split)[1], sort map { (my $s=$_) =~ s/(\d+)/sprintf '%06d', $1/ge; "$s $_"; } @data; __END__

Of course this is exclusively for illustrational purposes. In more complex or realistic situations he will have to find a suitable separator, provided that this is possible, and maybe he will have to work with index and substr instead, although pattern matching should be already optimized on fixed strings (as opposed to "real" patterns).

Oh, and of course he must know in advance that the size of his numbers has an upper bound, which seems to be the case.

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