JOINS are used in SQL to combine data from two or more tables based on a related column.

• Inner JOIN returns only the matching rows from both tables

• Equi JOIN is a type of Inner JOIN where the join condition is based on equality between two columns

• Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column

Divide array in two halves and keep each half in ascending order without using new Array.

• Use Array.sort() method to sort the original array

• Use Array.slice() method to divide the array into two halves

• Use Array.reverse() method to reverse the second half of the array

Interfaces are contracts that define a set of methods and properties that a class must implement.

• Interfaces provide a way to achieve abstraction and polymorphism in object-oriented programming.

• They allow for loose coupling between classes and promote code reusability.

• Interfaces can be used to define common behavior across multiple classes.

• Example: IDisposable interface in C# ensures that an object can be properly dispo...read more

Inheritance is a mechanism in object-oriented programming where a class is based on another class.

• Inheritance allows a subclass to inherit properties and methods from a superclass.

• The subclass can also add its own properties and methods.

• Examples include a Car class inheriting from a Vehicle class, or a Dog class inheriting from an Animal class.

To retrieve data from the back end, you can use APIs or database queries.

• Use API calls to fetch data from the back end server.

• Execute database queries to retrieve data from the database.

• Parse the response or query result to extract the required data.

• Handle any necessary authentication or authorization for accessing the back end.

• Examples: GET request to an API endpoint, SELECT query in SQL.

OOP is a programming paradigm based on the concept of objects, which can contain data and code.

• OOP stands for Object-Oriented Programming

• It focuses on creating objects that interact with each other to solve a problem

• Encapsulation, inheritance, and polymorphism are key concepts in OOP

• Example: A car object can have properties like color, make, and model, and methods like start and stop

• OOP promotes code reusability and ma

A program to check if a given number is prime or not.

• A prime number is a number that is only divisible by 1 and itself.

• Start checking from 2 up to the square root of the number.

• If the number is divisible by any number in the range, it is not prime.

• Otherwise, it is prime.

• Optimization: check only odd numbers after 2.

Fibonacci program generates a series of numbers where each number is the sum of the two preceding ones.

• The program can be implemented using recursion or iteration.

• The first two numbers in the series are always 0 and 1.

• The next number is the sum of the previous two numbers.

• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418,...read more
