Random String MD5, Complex Calculations, and File Analysis

The function first generates a random string, then gets the current time, calculates the MD5 value of the string, and saves the relevant information to a JSON file. Then it uses regular expressions to match numbers in the string, calculates the average, and calculates the square root of a complex number. Finally, it encodes the complex number result into a Base64 string, retrieves content from a URL, and calculates the sum of the lengths of all filenames in the current directory.
