prompt: Your task is to convert the following English description into an ASCII tree format.
  
  internal is a principal directory that gathers 2 subdirectories: enterprise and scan.
  At the top level, 'enterprise' bundles 2 folders: exceptions, impl.
  Within directory hierarchy 'enterprise > exceptions', The 'exceptions' storage space has no folders inside.
  In nested path 'enterprise > impl', Inside 'impl', you'll find it remains unused.
  Back to the top level.
  In the root directory, 'scan' holds 1 directories: config.
  Within directory hierarchy 'scan → config', Inside 'config', you'll find it is devoid of content.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  logical-expression
   +--deopzimize-while-included
   +--mutate-logical-expression
   |   `--_expected
   `--simplify-non-boolean
  ```
