This is untested, but the following can probably happen:

Change the outer for loop to a map (1 character)
Change the /^$/ to just $_ (2 characters)
Change the @{$w[-1]} to @{pop@w} (1 character)
Drop the semi-colon after the inner for loop (1 character)

Which gives us:

#234567890123456789012345678901234567890123456789012345678901234567890
+12
map{$n=$o=$_;for$c(@_){$n+=s/$c//}$_&&push@{$w[$n]},$o}<D>;@{pop@w}

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
