Can you explain what the DRY principle means in software development?

The DRY principle (Don't Repeat Yourself) in software development means that the same logic or code should not be duplicated in different parts of the program.

This helps to:

• reduce the number of errors, as changes need to be made in one place;
• improve code readability and maintainability;
• enhance the structure and architecture of the application.

For example, instead of copying the same code in multiple methods, it is better to extract it into a separate function and call it where needed.
