Don't Over think. Essentially it's just a pointer to a pointer.

char** x( char* my_str, int size)
	{
		char** double_ptr = new char*[size];

		for( int i = 0; i < size; i++)
		{
			double_ptr[i] = my_str + (size - (i +1));
			std::cout << *double_ptr[i];
		}
		return double_ptr;
	}

There's quite an extended back and forth in actual interviews for questions like this, so nothing quite like real practice.
