Car Mileage Tracking

You are managing a fleet of cars, and you need to keep track of the mileage of each car after a series of trips. Your input will be the mileage recorded after each trip for a specific car. Create a program that computes the cumulative mileage for that car after each trip and outputs it. Input: - The first line contains an integer M (1 <= M <= 100), the number of trips. - The second line contains M space-separated integers representing the mileage added after each trip. Output: - Print M space-separated integers where the i-th integer represents the total cumulative mileage after the i-th trip. Example Input: 4 50 30 20 100 Example Output: 50 80 100 200
