prompt: Your task is to convert the following English description into an ASCII tree format.
  
  platform is a parent directory that bundles 3 subdirectories: browser, common and node.
  At the main level, 'browser' shelters 1 subfolders: classes.
  In nested path 'browser → classes', Inside 'classes', you'll find it has nothing inside.
  Back to the top level.
  At the top level, Inside 'common', you'll find it is a vacant space.
  At the main level, 'node' organizes 1 nested folders: classes.
  In nested path 'node / classes', Inside 'classes', you'll find it has been left empty.
  Back to the top level.
