Random String Generator with Advanced Operations

The function generates a random string, calculates the square sum of two parameters, gets the current time, checks if the string contains only letters, counts the occurrences of characters in the string, generates the MD5 hash of the string, performs a unit test, copies an object, generates a file path, writes the string to the standard output, and writes the string to a file object in memory.
