I've read your question three times, and I don't have an answer, but I want to make sure I understand the question.

The data involved are:

  1. A secret number
  2. A guess at what the secret number is (e.g., 1122)
  3. Some description of how the guess matches the secret number (e.g., two of the digits are in the secret number in the place that they were in the guess, and one of the digits is in the secret number but not in the place that it was in the guess).

What you want is a regular expression that will match every possible number that the secret number could be, given the data you have.

Additionally, you want to be able to add (1) another guess, and (2) more data about how that guess matches, and refine the regex further.

Is that correct?

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.
