What is lsp in computer?

LSP, or the Liskov Substitution Principle, is a key concept in object-oriented programming that states objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program. This principle ensures that subclasses extend the functionality of a superclass while maintaining its behavior, promoting code reusability and robustness. Adhering to LSP helps prevent errors and enhances system maintainability by ensuring that derived classes are truly substitutable for their base classes.
