Depending how your building your data structure, it might make more sense to only add an array to @D, if that array has no duplicates. It being easier to not add it than to later remove it.

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

  • 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! —
