prompt: Your task is to convert the following English description into an ASCII tree format.
  
  route-indexes is a parent directory that collects 2 subdirectories: pages and test.
  At the main level, 'pages' shelters 3 subdirectories: api, nested-index, sub.
  In nested path 'pages > api', 'api' retains 1 subdirectory elements: sub.
  In nested path 'pages → api → sub', The 'sub' compartment is empty.
  Within directory hierarchy 'pages → nested-index', 'nested-index' keeps 1 child directories: index.
  In nested path 'pages / nested-index / index', Inside 'index', you'll find it is currently empty.
  Within directory hierarchy 'pages / sub', 'sub' appears to be unused.
  At the top level, Inside 'test', you'll find it is unpopulated.
  
  
  Format your response in this style:
  ```
  gradle
   +--api
   +--internal
   `--util
       `--internal
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
