Interface Method Returning a Boolean

The interface INumberChecker declares bool IsEven(int n). Complete the NumberChecker class so IsEven returns true when n is even and false otherwise. Do NOT write a Main method.

Note that C# prints booleans as True and False. For IsEven(4) the program prints the output shown in Expected Output.

Expected Output:

True↵

= newline. The output ends with a newline — print one after the last line.
