In this problem, you will create a program that implements a Card base class with GoldCard and SilverCard subclasses, uses polymorphism to store different card types in a Card[] array based on input, iterates through them calling the polymorphic methods getType() and getPoints() on each card, and displays the result to standard output.

Read the number of cards n and each card type (G or S) from standard input. Create a Card base class with GoldCard and SilverCard subclasses. Store the corresponding card types in a Card[] array and iterate through them, calling polymorphic methods getType() and getPoints() on each.

Input format:

• Line 1: number of cards n
• Next n lines: card type for each card (G: GoldCard, S: SilverCard)

Output format:

• For each card: [type]: [points] points on its own line
