✨ Key Features

• User-Friendly Interface: Allows users to upload text files or paste word lists directly.
• Comprehensive Analysis: Provides a detailed report that includes:
  • Internally Duplicated Words: Identifies words that are repeated within each list.
  • Exclusive Words: Shows words that are only in List 1 or only in List 2.
  • Common Words: Lists words that appear in both lists, indicating their first position and number of repetitions.
• Data Normalization: Performs case-insensitive comparisons and cleans content by removing whitespace and empty lines.
• File Generation: Allows the creation of a text file (newlist.txt) with words found in both lists.
• List Unification: Offers the option to display a unified list with all unique words from both lists.

🛠️ Project Structure

• index.php: Contains the user interface (HTML) and the logic to process form data. This is the main file users interact with.
• ListComparator.php: Defines the ListComparator class, which encapsulates all the business logic: data normalization, list comparison, repetition counting, and the creation of the new text file.
