Task 2. Safe-T-Cam

Available Marks: 9

Drivers slow down briefly for marked speed cameras, but calculating average speeds between checkpoints can be a more effective way of detecting consistently speeding vehicles.

Assume there are three checkpoints numbered 1, 2 and 3, spaced along a highway with a 110km/hr speed limit. Checkpoints 1 and 2 are 133.0 km apart and checkpoints 2 and 3 are 57.5km apart. Each checkpoint has an accurate clock and reliable numberplate recognition equipment. After each vehicle passes, the time, checkpoint number and numberplate are sent to a central log.

Your task is to read the log and identify any speeding vehicles.

The data is presented as a single file with the rows in strict time order, preceded by the number of rows on the first line (up to 300). Each data item consists of three fields, separated by a space:

You can assume the supplied data uses the correct format, all times are legitimate and so on.

The program's output consists of only the rows that indicate that a vehicle's average speed has exceeded the speed limit for the section that ends at that checkpoint, along with the calculated average speed in km/hr to 1 decimal place.

The output must be in chronological order, same as the input.

Example

Input:
