If this is going to be used a lot, I'd either stuff the dictionary file into a database, or else construct an index to the offsets and sizes of initial letter sections of the dictionary file.

Assuming the dictionary file is alphabetically sorted, you don't need to slurp the whole file into an array. That is a large chunk of memory for a million words. Allocations that size will slow you painfully if you are driven into swap.

Try just building an array with the a's, shuffling, and taking the first hundred elements. Then discard the a's and replace with the b's, all in a while loop that only reads one line at a time.

You don't need a loop to pick the first hundred elements of an array. A slice will do,

@array[0..99]
and is much faster.

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.
