This challenge includes several types of data items: advanced emails with special characters (e.g., apostrophes and plus signs), international phone numbers with optional parentheses and spaces, dates in multiple formats (using slashes, hyphens, periods), URLs with ports and query strings, and alphanumeric codes with dashes.
