You have a card game where each card has a color and an acquisition cost in gems. The card colors can be: G (Green), B (Blue), R (Red), Y (Yellow), P (Purple). The acquisition cost is represented by pairs of numbers and letters indicating the required quantity of gems of each color.

• Top right corner: G

• Bottom left corner: 1R2G3B (1 red gem, 2 green gems, 3 blue gems)

• The player has a balance of gems and a deck of cards.
• The gem balance and the deck of cards are independent.

1. Function can_purchase: Develop a function/method can_purchase that checks if a player can purchase a card based on their available gem balance.

2. Function purchase: Develop a function/method purchase that deducts the gem balance of the player when purchasing a card and adds the card to the player's deck, provided they have sufficient balance.
