Your question is Parking Lot Gate Control. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you wrote code to manage a parking lot with one entry gate and one exit gate using sensor and gate interfaces like get_sensor_1(), get_sensor_2(), open_gate_1(), and open_gate_2().
