We want to build a cab booking platform to allow a rider to book a cab.

• The location is represented as a (x, y) coordinate.
• Distance between two points (x1, y1) and(x2, y2) is sqrt((x1-x2)^2 + (y1-y2)^2)
• Platform has decided upon maximum distance a driver has to travel to pickup a rider.
• A cab has only 1 driver.
• Sharing of cab is not allowed between riders
• There is a single type of cab

Please build an application that exposes following features to riders and drivers.

• Register a rider.
• Register a driver/cab
• Update a cab's location
• A driver can switch on/off his availability
• A rider can book a cab
• Fetch history of all rides taken by a rider.
• End the Trip

• Demonstrable code is first expectation. To do this, you can choose any interface you are comfortable with - CLI, WebApp, MobileApp, APIs or even simply run the code via Tests or a main method.
• Code should be extensible.
• Clean professional level code.
• Functional Completeness including good modelling.
• User Identification but not authentication.
• Backend Database is optional. However modelling should be complete.
