Behavioral interview questions

1. A.a pattern that passes a request along a chain of handlers until one of them handles it, decoupling sender from receiver
2. B.a pattern that encapsulates a request as an object, letting you parameterize, queue, log, and undo operations
3. C.a pattern that captures and externalizes an object's internal state so it can be restored later without violating encapsulation
4. D.a pattern that defines a one-to-many dependency so when one object changes state all its dependents are notified automatically, the basis of pub-sub

2. B.Observer — a pattern that captures and externalizes an object's internal state so it can be restored later without violating encapsulation
3. C.Observer — a pattern that defines a one-to-many dependency so when one object changes state all its dependents are notified automatically, the basis of pub-sub
4. D.Observer — a pattern that passes a request along a chain of handlers until one of them handles it, decoupling sender from receiver

1. A.a pattern that passes a request along a chain of handlers until one of them handles it, decoupling sender from receiver
2. B.a pattern that defines a family of interchangeable algorithms, encapsulates each one, and lets the algorithm vary independently from clients that use it
3. C.a pattern that centralizes complex communication between objects in one mediating object so they no longer refer to each other directly
