Welcome to LLD 101! In this guided tutorial, we will design a Parking Lot System. We will walk through the process of identifying actors, defining responsibilities, and creating a flexible design using Design Patterns.

What You'll Build

The parking lot should have multiple levels, each level with a certain number of parking spots.
The parking lot should support different types of vehicles, such as cars, motorcycles, and trucks.
Each parking spot should be able to accommodate a specific type (size) of vehicle.
The system should assign a parking spot to a vehicle upon entry and release it when the vehicle exits.
The system should track the availability of parking spots and provide real-time information to customers.
...and more
