hard🎤 Interviewer Follow-up Q10 of Q15
Step-by-Step Solution
Solution:
Step 1: Identify need for polymorphism
Different player types require different move logic.Step 2: Use interface for extensibility
Player interface with HumanPlayer and AIPlayer subclasses cleanly separates behaviors.Step 3: Evaluate other options
Embedding AI logic in Player class mixes concerns; GameController handling AI breaks single responsibility; global AI manager complicates design.Final Answer:
Option D -> Option DQuick Check:
Interface supports multiple player types [OK]
Quick Trick: Separate classes for AI and human players [OK]
Common Mistakes:
MISTAKES- Mixing AI logic inside Player class
- Overloading GameController with AI logic
- Using global manager causing tight coupling
Trap Explanation:
PITFALL- Candidates often choose quick fixes that reduce modularity and increase coupling, hurting maintainability.
Interviewer Note:
CONTEXT- Assesses design for extensibility and clean separation of concerns
