LLD - Design — Chess GameHow would you combine game state management with event-driven architecture to improve scalability in a multiplayer game?AUse event queues to broadcast state changes asynchronously to all clientsBStore all states in a single global variable accessed by all threadsCUse blocking calls to update states synchronously for each playerDSend state changes only when the game endsCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand event-driven architecture benefitsIt decouples components and allows asynchronous communication, improving scalability.Step 2: Apply to game state managementUsing event queues to broadcast state changes lets multiple clients update independently and efficiently.Final Answer:Use event queues to broadcast state changes asynchronously to all clients -> Option AQuick Check:Event-driven + state = async broadcast [OK]Quick Trick: Broadcast state changes asynchronously for scalability [OK]Common Mistakes:Using global variables causing race conditionsBlocking calls reducing performanceDelaying updates until game ends
