Query to find employees in the same department as the highest-paid employee.
Use a subquery to find the highest salary: SELECT MAX(salary) FROM employees.
Join the employees table with itself to filter by department.
Example query: SELECT name FROM employees WHERE department_id = (SELECT department_id FROM employees WHERE salary = (SELECT MAX(salary) FROM employees));
Extracting the domain name from an email ID involves parsing the string after the '@' symbol.
Use string manipulation functions to split the email ID at the '@' symbol.
For example, for 'user@example.com', the domain is 'example.com'.
In SQL, you can use SUBSTRING_INDEX(email, '@', -1) to get the domain.
In Python, you can use email.split('@')[1] to extract the domain.
Handling high traffic in a Node.js application involves optimizing performance, scaling, and managing resources effectively.
Load Balancing: Distribute incoming traffic across multiple server instances using tools like Nginx or AWS Elastic Load Balancing.

For example, an input field that allows users to enter comments could be v...
CSP header bypass involves exploiting misconfigurations or weaknesses in Content Security Policy to execute unauthorized scripts.
1. Use of 'unsafe-inline': If a CSP allows 'unsafe-inline', attackers can inject scripts directly into HTML.
2. Whitelisting domains: If a CSP whitelists a domain that is compromised, attackers can serve malicious scripts from that domain.
3. Data URIs: Some CSP configurations may allow da...

Declare variables for first and second numbers in the series
Loop through the desired number of iterations
Calculate the next number in the series by adding the previous two
Print or store the result
- Q5. Write even and odd number code
- Ans.
Code to print even and odd numbers
Use a loop to iterate through numbers
Check if the number is even or odd using modulus operator
Print the number accordingly
- Q6. How to write excute parameters in function
- Ans.
Execute parameters in a function must be an array of strings.
Define the function with parameters in the parentheses
Separate each parameter with a comma
Enclose the parameters in square brackets to create an array
Example: function myFunction([param1, param2, param3]) { //code here }
- Q7. Explain about Oops concept
- Ans.
OOPs is a programming paradigm based on the concept of objects that interact with each other.
OOPs stands for Object-Oriented Programming.
It focuses on creating objects that have properties and methods.
Encapsulation, Inheritance, and Polymorphism are the three main pillars of OOPs.
Encapsulation is the process of hiding the implementation details of an object from the outside world.
Inheritance allows a class to inherit p...
- Q8. Why we use class explain with example
- Ans.
Classes are used in object-oriented programming to define a blueprint for creating objects.
Classes provide encapsulation, inheritance, and polymorphism.
They help organize code and make it more reusable.
Example: class Car { String make; int year; }
Example: Car myCar = new Car(); myCar.make = "Toyota"; myCar.year = 2021;
- Q9. What is anonymous function
- Ans.
An anonymous function is a function without a name.
Anonymous functions are often used as arguments to higher-order functions.
They can be defined using the function keyword or as arrow functions.
Example: const add = function(x, y) { return x + y; }
Example: const multiply = (x, y) => x * y;
- Q10. What is inheritance method
- Ans.
Inheritance is a mechanism in object-oriented programming where a class is derived from another class.
Inheritance allows a subclass to inherit properties and methods from a superclass.
The subclass can also add its own properties and methods.
Inheritance promotes code reuse and helps in creating a hierarchical class structure.
For example, a Car class can inherit from a Vehicle class, which can inherit from a Transport cl...
- Q11. Why python is a dynamic language
- Ans.
Python is a dynamic language because it allows for runtime changes and doesn't require variable declarations.
Python doesn't require variable declarations, allowing for dynamic typing
Functions and classes can be modified at runtime
Python's built-in functions like type() and setattr() allow for dynamic behavior
Dynamic behavior allows for more flexibility and faster development
Example: changing the type of a variable duri...
- Q12. What is data structures
- Ans.
Data structures are ways of organizing and storing data in a computer so that it can be accessed and used efficiently.
Data structures are used to manage and manipulate data in computer programs.
Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.
Choosing the right data structure for a particular problem can greatly improve the efficiency of a program.
Data structures can be implem...
- Q13. Difference between list and tuple
- Ans.
List is mutable while tuple is immutable in Python.
List can be modified while tuple cannot be modified.
List uses square brackets [] while tuple uses parentheses ().
List is slower than tuple in terms of performance.
List is used for collections of data while tuple is used for grouping related data.
Example of list: [1, 2, 3] and example of tuple: (1, 2, 3).
- Q14. How to convert dictionary into list
- Ans.
Convert dictionary to list in Python
Use the items() method to get key-value pairs as tuples
Convert the tuples to a list using list()
Append the lists to a new list using append()
Alternatively, use list comprehension to convert the dictionary to a list
- Q15. Explain about homogeneous elements
- Ans.
Homogeneous elements are elements of the same type or kind.
Homogeneous elements have similar properties and characteristics.
They can be combined or compared easily.
Examples include a set of integers, a group of apples, or a collection of red flowers.
- Q16. What is an array
- Ans.
An array is a collection of similar data types stored in contiguous memory locations.
Arrays can be of any data type, such as integers, floats, characters, etc.
Arrays are accessed using an index, starting from 0.
Arrays can be one-dimensional, two-dimensional, or multi-dimensional.
Example: string[] names = {"John", "Jane", "Bob"};
Example: int[] numbers = new int[5];
- Q17. How many times we use for loop in single program
- Ans.
The number of times a for loop is used in a program varies depending on the program's requirements.
The number of for loops used in a program depends on the program's logic and requirements.
For loops are used to iterate over arrays, lists, and other data structures.
Nested for loops are used to iterate over multi-dimensional arrays.
For loops can also be used for counting and other repetitive tasks.

- Q19. Prime number condition
- Ans.
Prime number is a number that is divisible only by 1 and itself.
Prime numbers are always greater than 1.
Examples of prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
To check if a number is prime, divide it by all numbers less than or equal to its square root. If none of them divide it evenly, it is prime.
