prompt: Your task is to convert the following English description into an ASCII tree format.
  
  main is a principal directory that bundles 2 subdirectories: java and resources.
  At the top level, 'java' retains 1 child directories: org.
  Within directory hierarchy 'java / org', 'org' holds 1 folders: gradle.
  In nested path 'java → org → gradle', 'gradle' bundles 1 folders: sample.
  Within directory hierarchy 'java > org > gradle > sample', 'sample' houses 2 directories: api, apiImpl.
  In nested path 'java → org → gradle → sample → api', The 'api' collection is empty.
  In nested path 'java / org / gradle / sample / apiImpl', The 'apiImpl' repository appears to be unused.
  Back to the top level.
  In the root directory, 'resources' incorporates 1 subdirectory elements: org.
  At level 2, in directory path 'resources / org', 'org' holds 1 subdirectory elements: gradle.
  Within directory hierarchy 'resources > org > gradle', The 'gradle' directory is a vacant space.
  Back to the top level.
