prompt: Your task is to convert the following English description into an ASCII tree format.
  
  groovy is a principal directory that maintains 2 subdirectories: src and test.
  In the root directory, 'src' encapsulates 1 subdirectories that organize the source code.
  At level 2, in directory path 'src / java', 'java' encompasses 1 contained folders: org.
  Within directory hierarchy 'src / java / org', 'org' organizes 1 directory entries: gradle.
  Within directory hierarchy 'src → java → org → gradle', 'gradle' is an empty container.
  Back to the top level.
  In the root directory, 'test' houses 1 folders for testing purposes.
  Within directory hierarchy 'test → java', 'java' hosts 1 directories: org.
  At level 3, in directory path 'test / java / org', 'org' houses 1 contained folders: gradle.
  In nested path 'test → java → org → gradle', Inside 'gradle', you'll find it is an empty container.
  Back to the top level.
