Object-oriented programming is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOP is a programming paradigm that uses objects to structure code
Objects have attributes (fields) and behaviors (methods)
Encapsulation, inheritance, and polymorphism are key principles of OOP
Example: A 'Car' object may have attributes like 'color' an...
The diamond problem occurs in multiple inheritance when a class inherits from two classes that share a common ancestor.
Involves ambiguity in method resolution when two parent classes have a method with the same name.
Example: Class A has a method 'display', and both Class B and Class C inherit from A and also have 'display'.
When Class D inherits from both B and C, it can lead to confusion about which 'display' meth...
Convert the number 121 into its English word representation: 'one hundred twenty-one'.
Break down the number into hundreds, tens, and units.
121 consists of 100 (one hundred) and 21 (twenty-one).
Combine the parts: 'one hundred' + 'twenty-one' = 'one hundred twenty-one'.
Find the third largest string in an array of strings.
Sort the array in descending order.
Skip the first two elements and return the third element.
Joins in SQL are used to combine rows from two or more tables based on a related column between them.
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
INNER JOIN returns rows when there is at least one match in both tables
LEFT JOIN returns all rows from the left table and the matched rows from the right table
RIGHT JOIN returns all rows from the right table and the matched rows from the left ta...
DML commands are Data Manipulation Language commands used to manage data in a database.
DML commands include INSERT, UPDATE, DELETE, and SELECT.
INSERT is used to add new rows of data into a table.
UPDATE is used to modify existing data in a table.
DELETE is used to remove rows of data from a table.
SELECT is used to retrieve data from a database.
Inner joins return matching records from both tables, while outer joins return all records from one table and matched records from the other.
Inner Join: Combines rows from two or more tables based on a related column. Example: SELECT * FROM A INNER JOIN B ON A.id = B.id;
Left Outer Join: Returns all records from the left table and matched records from the right table. Example: SELECT * FROM A LEFT JOIN B ON A.id = ...
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It allows for code reusability and flexibility.
Polymorphism can be achieved through method overriding and method overloading.
Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. T...
An abstract class is a class that cannot be instantiated and is used as a base for other classes.
An abstract class can have abstract methods that must be implemented by its subclasses.
It can also have non-abstract methods that can be inherited by its subclasses.
An abstract class provides a common interface for its subclasses.
It is used to achieve abstraction and provide a blueprint for other classes.

Breadth-First Search (BFS) explores nodes layer by layer in a graph, ideal for shortest path and connectivity problems.
BFS uses a queue to keep track of nodes to explore next.
It starts from a source node and explores all its neighbors before moving to the next level.
Example: In a social network graph, BFS can find the shortest path between two users.
BFS is useful for finding the shortest path in unweighted graphs.
It ca...

I appeared for an interview in Jun 2025, where I was asked the following questions.
Polyfills are scripts that enable modern web features in older browsers by providing fallback implementations.
Polyfills allow developers to use new JavaScript features like Promises or Fetch API in older browsers.
Example: A polyfill for the Array.prototype.includes method allows it to work in browsers that do not support it natively.
They are typically included in the codebase to ensure compatibility across different en...
call, apply, and bind are methods in JavaScript for controlling function context and arguments.
call: Invokes a function with a specified 'this' value and arguments. Example: func.call(obj, arg1, arg2).
apply: Similar to call, but takes an array of arguments. Example: func.apply(obj, [arg1, arg2]).
bind: Returns a new function with a specified 'this' value, allowing for partial application. Example: const boundFunc = func...
