Can you explain the Liskov Substitution Principle regarding replacing subclasses with base classes in object-oriented programming?

The Liskov Substitution Principle states that objects of a subclass should be interchangeable with objects of the base class without affecting the correctness of the program. This means that a subclass should preserve the behavior of the base class and not introduce unexpected changes, so that code using the base class can work with the subclass without errors and changes in logic.
