Thought, might be helpful to have a quick reference for some other readers...

Patrica Tree/Trie = "Practical Algorithm to Retrieve Info Coded In Alphanumeric," where Trie came from reTRIEval (pronounced either "tree" or "try")

Suppose you have data: good gal bad gag

How it looks like in a noncompact tree:

	         ^    ____ $ ___(NULL)
	     /  / \ \
	    b  g  g  g
	   /  /   |   \
	  a  a    a    o
	 /   |    |     \
	d    g    l      o
	|    |    |       \
	$    $    $       d
	|    |    |       |
         (bad)(gag)(gal)     $

How it looks like in a Patrica Tree

	       ^    ____ $ ___(NULL)
	     /    \ 
	    b     g 
	   /    /   \
	  a    a     o
	 /    |  \    \
	d     g   l    o
	|     |   |     \
	$     $   $     d
	|     |   |     |
         (bad)(gag) (gal)  $

I suppose most people know in this context DFA and NFA stand for "Deterministic Finite Automaton" and "Nondeterministic Finite Automaton" respectively, not "Dairy Farmers of America" and "National Farmers Association."

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.
