I wouldn't give up yet. You need to see an implementation and how it benchmarks.

Implementing Suffix Trees in pure perl is messy, memory expensive (hugely so in my attempts), and rarely works out more efficient. Don't forget that it's O(n) to build as well as O(m) to use. If you are only using it once, that snips into the benefits.

For short strings a linear search (at C speed) and no build time wins easily. For longer strings, the indexing a suffix tree provides is a winner, but it gets set back awfully by the build time and memory management. If you only use the tree the once (as for this challenge), there little or no win.


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

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.
