Round 2 - LLD/ Design Round

📌 LLD Question: Feature Toggle System

Design a Feature Toggle Service for an application (e.g., streaming platform like Netflix) that allows enabling or disabling features dynamically.

🧩 Requirements
The system should allow:

• Add, enable, disable, and remove features

Each feature may have rules:

• Subscription-based (e.g., Premium)
• Region-based (e.g., IN)
• If no rule → feature available to all users
• Check if a feature is enabled for a given user
