You are asked to create an object that should be instantiated only once and reused in other instances. Which design pattern would you implement?

In this scenario, you would implement the Singleton Pattern. The Singleton Pattern ensures that a class has only one instance and provides a global point of access to that instance. It's useful when you need to maintain a single instance of an object that is shared across multiple parts of your application. This can help in scenarios such as creating a global configuration or managing a resource pool.
