Constructor and Destructor Order

A base class Base has been provided with a constructor that prints "Base constructor" and a virtual destructor that prints "Base destructor".

A derived class Derived publicly inherits from Base.

Your task is to implement:
1. The Derived constructor - it should print "Derived constructor"
2. The Derived destructor - it should print "Derived destructor"

When a Derived object is created, the Base constructor runs first, then Derived. When destroyed, Derived destructor runs first, then Base.

Do NOT include a main function. Your code will be tested automatically.

Expected Output:

Base constructor↵
Derived constructor↵
Derived destructor↵
Base destructor↵

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