prompt: Your task is to convert the following English description into an ASCII tree format.
  
  monorepo is a top-level directory that collects 2 subdirectories: input and output.
  At the top level, 'input' carries 2 directories: app1, app2.
  In nested path 'input → app1', Inside 'app1', you'll find it is an empty container.
  At level 2, in directory path 'input → app2', The 'app2' compartment awaits content.
  At the main level, 'output' contains 2 contained folders: app1, app2.
  In nested path 'output > app1', The 'app1' container holds no subdirectories at the moment.
  At level 2, in directory path 'output > app2', The 'app2' data structure appears to be unused.
