Thanks for the suggestion

Imagine, for instance, a regexp like this

$pattern="[^D]{2,3}FGR{2}..H";

There is not fuzzyness on this. From a list of strings, some will match and some will NOT match this regular expression. The question is: considering ONLY substitutions, allow a maximum of 2 mismatches when evaluating if the string matches or not to $pattern. This will result in the migration of some strings from the 'non-matching group' to the 'matching group'.

How to do this in Perl?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • 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.
