User Guide:

1. Enter Regex Pattern: Start by typing your regex pattern into the "Regex Pattern" input field.

2. Input Sample Text: Paste or type the sample text you want to test your regex against in the "Sample Text" box.

3. Select Flags: Choose your desired matching flags by checking or unchecking the options:

   • Global (g): Finds all matches, not just the first.

   • Case Insensitive (i): Matches letters regardless of case.

   • Multi-line (m): Treats start and end characters (^ and $) as working across multiple lines.

4. View Results: As you type, the results will be displayed in real-time below, with the number of matches and the matched text highlighted in yellow.

5. Replace Matches: If you wish to replace the matched text, type the replacement string into the "Replace with" field and click "Replace". The modified text will be displayed, and the sample text will be updated accordingly.

6. Start Over: If you need to reset everything, simply clear the input fields and start over with a new pattern or text.
