  Instructions:
  1. Create a class named ReversedString that inherits from StringOperations class
  2. Implement the function reverse
  3. reverse function should be a one liner function that returns the reverse string to_be_reversed
  4. Instantiate the class ReversedString
  5. Print to show your function implementation result
