What is the role of SOLID principles in developing quality software?

The SOLID principles play a key role in creating high-quality, maintainable, and extendable software. They help:

• S (Single Responsibility Principle) — each class or module is responsible for one task, which simplifies understanding and modifying the code.
• O (Open/Closed Principle) — software entities are open for extension but closed for modification, reducing the risk of errors when adding new features.
• L (Liskov Substitution Principle) — subclasses can replace base classes without breaking the program, ensuring reliability and flexibility.
• I (Interface Segregation Principle) — it's better to create several specialized interfaces than one universal one, making the code more understandable and adaptable.
• D (Dependency Inversion Principle) — high-level modules do not depend on low-level modules; both depend on abstractions, which facilitates testing and component replacement.

Applying SOLID reduces technical debt and makes code maintenance easier.
