Function xxx: Random String, File Listing, Number Extraction, and JSON Creation

This code defines a function xxx that generates a random string, lists all files in a specified directory, extracts numbers from a string, calculates the average of those numbers, creates a JSON data containing this information, and returns the JSON data and the reverse of the input string.
