Nested JSON Parsing for Licensing | Dataford Interview Questions

Each region may use name or region; missing names should be Unknown region, and null values should be N/A. Format nested dictionaries and lists recursively, preserving sorted object keys. Return No regional requirements found. when regions is missing or empty.
