Kudos for mentioning up front that this is a learning exercise. That makes the somewhat odd requirements less of a distraction. It also means that my suggestion will apply to your current approach rather than trying to change it.

Since you've got the dictionary words alphabetized in an array, you could use a binary search to determine if a word in your corpus is in the array. You should be able to find some things around here on that pretty easily if you use Super Search and sprinkle with key words liberally.

Good luck

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.
  • Please read these before you post! —
