prompt: Your task is to convert the following English description into an ASCII tree format.
  
  impl is a central directory that contains 3 subdirectories: fingerprint, problems and serialization.
  In the root directory, The 'fingerprint' container is a vacant space.
  At the top level, Inside 'problems', you'll find it hasn't been filled with any content.
  In the root directory, 'serialization' carries 1 directories: codecs.
  In nested path 'serialization > codecs', The 'codecs' collection appears to be unused.
  Back to the top level.
  
  
  Format your response in this style:
  ```
