Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness.

• Subtypes must be substitutable for their base types.

• Derived classes should be able to extend the functionality of base classes without changing their behavior.

• Violating this principle can lead to unexpected behavior in the program.

• Example: If a Square class inherits from a Rectangle class, it should be able to subst...read more

I connect my code to the database using a repository pattern. Group By can work without having an explicit repository.

• I use a repository pattern to abstract the database operations in my code.

• I typically use Entity Framework as my ORM to connect to the database.

• Group By can work without having an explicit repository by directly querying the database using LINQ or SQL.

Segregate odd and even numbers in an integer array without using another array

• Iterate through the array and maintain two pointers, one for odd numbers and one for even numbers

• Swap elements at the odd and even pointers until all odd numbers are on one side and even numbers on the other

• Example: Input array [3, 6, 8, 5, 4], Output array [6, 8, 4, 5, 3]

Unit testing is crucial in ensuring clean code by verifying the functionality of individual units of code.

• Unit testing helps in identifying bugs and errors early in the development process.

• It ensures that each unit of code works as expected in isolation.

• Unit tests act as documentation for the codebase, making it easier for new developers to understand and modify the code.

• It promotes code reusability and maintainability by allowing developers to make changes confidently withou...read more

A trigger is a special type of stored procedure that is automatically executed when certain events occur in a database.

• Triggers are used to enforce business rules, perform auditing, and maintain data integrity.

• Configuration for triggers is typically available in the database management system where the trigger is created.

• Examples of trigger events include INSERT, UPDATE, and DELETE operations on a table.

Abstraction is crucial in software development to simplify complexity, improve readability, and promote reusability.

• Abstraction helps in hiding unnecessary details and focusing on essential features.

• It allows developers to work at a higher level of understanding without getting bogged down in implementation details.

• Abstraction promotes code reusability by creating modular and reusable components.

• It improves code readability and maintainability by organizing code into logical ...read more

Polymorphism is the ability of a single function or method to operate on different data types.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example of compile-time polymorphism: function overloading in Java.

• Example of runtime polymorphism: method overriding in Java.

• Polymorphism helps in achieving flexibility and reusability ...read more
