The InstantRide Driver Relationship team wants to create groups for drivers according to their ratings such as 3+ or 4+. For instance, a driver with the rating 3.8 will be 3+; whereas a driver with the rating 4.2 will be 4+. You need to return a two column output with DRIVER_ID and DRIVER_RATING which has first FLOOR applied and then CONCAT with + sign for all drivers with a rating greater than 0.

Running Time of Application

The application has a feature called running time. It is one of the parameters for measuring its performance. It is written in a particular language and is designed to perform a specific task. Applications run in a specific environment. The execution of the business will depend on the application’s running time. It must be optimized in order to get the maximum benefits out of the application.
