Optimal approach for checking if a number is prime or not using DSA
Optimal approach for checking prime numbers is to iterate up to square root of the number
Use trial division method to check divisibility by numbers up to square root of the number
Time complexity of this approach is O(sqrt(n))
A class is a blueprint for creating objects, which are instances of the class. Objects have attributes and behaviors.
Classes define the structure and behavior of objects.
Objects are instances of classes and have their own unique attributes and behaviors.
Example: Class 'Car' with attributes like 'color' and behaviors like 'drive'. Object 'myCar' is an instance of 'Car' with color 'red' and can drive.
Example: Class 'Pers...
SQL normal forms are levels of organization for relational databases to reduce redundancy and improve data integrity.
First normal form (1NF) - Eliminate repeating groups and ensure each column contains atomic values.
Second normal form (2NF) - Meet 1NF requirements and have all non-key attributes fully functionally dependent on the primary key.
Third normal form (3NF) - Meet 2NF requirements and have no transitive depend...
