abstract class: Vehicle Definition

In this problem, you will create a program that defines an abstract class Vehicle with an abstract method move(int speed), overrides it in both Car and Bike classes, and displays each vehicle's speed to standard output.

Learning Objective: Define common interface using abstract class and abstract methods

Create a vehicle abstract class. Define abstract methods and implement in Car and Bike.

Input

Line 1: Car speed (integer)
Line 2: Bike speed (integer)

Output

Car running at [speed] km/h
Bike running at [speed] km/h
