What will be the output of the following C++ code?

#include <iostream>
using namespace std;
struct A
{
    virtual ~A()
    { 
        cout << "~A()" << endl; 
    }
    void operator delete[](void* p, size_t)
    {
        cout << "A :: operator delete[]" << endl;
        delete [] p;
    }
};
struct B : A 
{
    void operator delete[](void* p, size_t) 
    {
        cout << "B :: operator delete[]" << endl;
        delete [] p;
    }
};
int main() 
{
    A* bp = new B[3];
    delete[] bp;
};
