Define a public class named Stepper with a single instance method named next that takes no parameters and returns an Int. Called multiple times, next returns a sequence of values separated by a step amount provided to the primary constructor. Stepper should also provide a primary constructor that accepts a Int argument and sets the step amount. Stepper maintains two pieces of private state: the step amount, and the current value, which always starts at 0 . The step amount is passed to the constructor, and should be part of your primary constructor declaration. But the current value should be declared separately. Calling next increments the current value by the step amount, but returns the previous value. So, for example: Note that the internal state should be private
