prompt: Your task is to convert the following English description into an ASCII tree format.
  
  _expected is a source directory that holds 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the organization for you:
  
  At the top level, 'amd' features 1 subfolders: nested.
  In nested path 'amd / nested', The 'nested' container stands empty.
  Back to the top level.
  In the root directory, 'cjs' carries 1 subdirectory elements: nested.
  Within directory hierarchy 'cjs → nested', 'nested' has been left empty.
  Back to the top level.
  At the top level, 'es' groups 1 subdirectory elements: nested.
  Within directory hierarchy 'es > nested', Inside 'nested', you'll find it has nothing inside.
  At the top level, 'system' houses 1 child directories: nested.
  In nested path 'system → nested', Inside 'nested', you'll find it holds no subdirectories at the moment.
  
  
  Format your response in this style:
  ```
  main
   +--java
   |   `--org
   |       `--gradle
   |           `--sample
   `--webapp
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
