Consider the following Python code implementing the Strategy Pattern for payment processing:

class PaymentStrategy:
    def pay(self, amount):
        pass

class CreditCardStrategy(PaymentStrategy):
    def pay(self, amount):
        print(f"Paid ${amount} using Credit Card")

class PaymentProcessor:
    def __init__(self, strategy):
        self.strategy = strategy
    def pay(self, amount):
        self.strategy.pay(amount)

processor = PaymentProcessor(CreditCardStrategy())
processor.pay(100)

What will be the output when the last line is executed?
