The deep-sea research station, "Aquarius-7", operates an automated airlock entry system for its high-security Hydro-thermal Lab.

Submersibles have one of four security clearance classes: Alpha, Beta, Gamma, or Delta.

Only submersibles with 'Beta' or 'Gamma' clearance are authorised to dock in the Hydro-thermal Lab. Furthermore, due to safety regulations, the lab has a strict capacity limit of 8 submersibles at any one time.

Draw a flowchart to represent the automated process of checking and processing a docking request for the lab.

Your flowchart must:

  • Input the submersible's clearance class and the current number of submersibles currently docked in the lab.
  • Check if the submersible's clearance class is authorised ('Beta' or 'Gamma').
  • Check if there is space available (less than 8 submersibles).
  • Output an appropriate message if the submersible is unauthorised, if the lab is at full capacity, or if the docking request is granted.
