Update BlackjackGame.py (DhanushNehru#263)
1. Enhanced Betting Functionality: Valid Bet Validation: The placeBet() method now ensures that players enter valid bets within the specified range and that they have sufficient funds. Clear Error Messages: Informative messages are provided for invalid inputs or insufficient funds. 2. Improved Card Handling: Ace Value Adjustment: The adjustAceValue() method correctly handles cases where an ace's value should be reduced to 1 to prevent a bust. . Enhanced Game Logic: Simplified Winner Determination: The playRound3() method now uses a separate determine_winner() function to improve code readability and maintainability. 4. Additional Features: Initial Bankroll: Players now start with an initial bankroll of 1000 units. Betting Limits: Minimum and maximum betting limits have been introduced.
