- Q3. Give example of any design pattern
- Ans.
One example of a design pattern is the Singleton pattern.

It involves a static method to access the instance and a private constructor to prevent instantiation from other classes.
Example: Singleton pattern is commonly used in logging classes, database connections, and thread pools.
