• Polymorphism makes code more flexible and reusable.

Dynamic binding is the process of linking a method call to the method implementation at runtime.

• Dynamic binding allows the method implementation to be determined at runtime based on the actual type of the object.

• It is also known as late binding or runtime polymorphism.

• Example: In Java, when a method is overridden in a subclass, the method call is dynamically bound to the subclass implementation at runtime.

Identifying a loop in a linked list
