Food Delivery Dashboard with Driver Cost and Payment Tracking

rippling Please build a food delivery dashboard system with the following functionalities: Function Definitions add_driver(driver_id, hourly_rate): Add a driver with a specific hourly rate. record_delivery(driver_id, start_time, end_time): Record a completed delivery with the assigned driver and the delivery's start and end times. get_total_cost(): Return the total cost of all deliveries so far. Advanced Functionality pay_up_to(pay_time): Calculate and mark as paid all costs up to a certain time. get_total_cost_unpaid(): Return the total cost of all unpaid deliveries. Notes Time is represented as a 24-hour format string, e.g., '14:30'. Ensure that all input parameters are valid and consider the accumulation of costs for different drivers. Provide operational examples and verify their correctness. Example Input add_driver(1,10) record_delivery(1,'13:00','15:00') get_total_cost() pay_up_to('15:00') get_total_cost_unpaid()
