Chain of Responsibility

The Chain of Responsibility is a design pattern where a request is passed along a chain of objects, each capable of handling it. If one object can’t handle the request, it moves to the next until someone responds. This approach distributes processing across multiple handlers, making systems more flexible and manageable. It’s useful in scenarios like customer support, event handling, or logging, where the responsibility for dealing with a request can be shared among several components rather than a single one.
