Count completed trips from vehicle event logs (entry -> road -> exit)

Problem You are given text logs for multiple vehicles (each record includes a license plate and an event type). Event types are: entry, road, exit. A trip is counted when the same plate appears in chronological order with a complete sequence: entry -> road -> exit Implement get_trip(logs) (or an equivalent program) to return the total number of completed trips. Input A list/stream of log records in time order. Each record contains at least: plate and event. Output An integer: total number of completed trips. Notes / Assumptions Only full entry -> road -> exit sequences count. The same plate may complete multiple trips. Explain how you handle invalid or incomplete sequences (e.g., missing entry, repeated entry, exit before entry). Sample Tests (illustrative) (Using plate event per line; actual interview format may differ.) A entry A road A exit Output: 1 A entry A exit A road Output: 0 A entry A road A exit A entry A road A exit Output: 2 A road A exit Output: 0 A entry B entry A road B road A exit B exit Output: 2 Example Input 3 A entry A road A exit Output 1
