Build a helper function that simplifies extracting data from a string using a regular expression. This would be especially useful for parsing logs, validating formats, or extracting structured data from unstructured text. Takes in a text input and a regular expression. Returns the first matched group from the regex. If no match is found, return null. String getText(String input, String regex) Ex. getText("User: John, Age: 30", "User: (\\w+)") // Output: "John" Benefit: This function simplifies data extraction from unstructured text, accelerating development and reducing errors in input parsing and validation workflows.
