---------------------- 
|                    |
|                    |

Considerations

• MVC (Model-View-Controller) design pattern to achieve separation of concerns
• Outside-in TDD approach for practice purposes (as set in the requirements)
• Edge-cases and error handling:
  • Will accept command in both upper and lowercase. Both c 20 4 and C 20 4 are valid.
  • If an invalid command is entered, the user will be prompted to retry until a valid command is entered.
