prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
  
  Convert this description:
  
  src is a primary directory that consolidates 2 subdirectories: common and math.
  At the main level, 'common' retains 3 child directories: filters, interceptors, strategies.
  Within directory hierarchy 'common / filters', 'filters' hasn't been filled with any content.
  At level 2, in directory path 'common > interceptors', 'interceptors' awaits content.
  Within directory hierarchy 'common / strategies', The 'strategies' data structure is barren.
  Back to the top level.
  In the root directory, The 'math' data structure is devoid of content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
