( [id://3333]=superdoc: print w/replies, xml ) Need Help??

thundergnat's solution is the best I can see (I came up with it independently) because it avoids the ugly removal of every 2nd item. However, because variety is the spice of life I present the ganglier:

my @runs = do { my $i; grep ++$i%2, split /(?<=(.))(?!\1)/, 'aaabbcddd +daee' };
which suffers from the same annoyance as your original solution: the parens, which are needed for the back reference, have the annoying side effect here of changing the semantics of what split returns.

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.
