Q1. What are the Aggregate functions in sql
Aggregate functions in SQL are used to perform calculations on a set of values and return a single value.
Common aggregate functions include SUM, AVG, COUNT, MAX, and MIN.
SUM calculates the total of a set of values.
AVG calculates the average of a set of values.
COUNT counts the number of values in a set.
MAX returns the highest value in a set.
MIN returns the lowest value in a set.

Q3. What is oops what are pillars of oops what is list and tuples
OOPs stands for Object-Oriented Programming. Pillars of OOPs are Inheritance, Encapsulation, Abstraction, and Polymorphism. Lists and tuples are data structures in Python.

Pillars of OOPs are Inheritance, Encapsulation, Abstraction, and Polymorphism
Lists and tuples are data structures in Python
Lists are mutable while tuples are immutable
Q4. Write a recursion program.
A recursion program is a function that calls itself until a base case is reached.
Identify the base case and write the code to handle it
Write the recursive case that calls the function with a modified input
Ensure the recursive case moves towards the base case
Example: Factorial function: function factorial(n) { if (n === 0) { return 1; } else { return n * factorial(n-1); } }
Example: Fibonacci sequence: function fibonacci(n) { if (n <= 1) { return n; } else { return fibonacci(n-...read more
Q5. Remove duplicate from array
Remove duplicates from an array
Use a loop to iterate through the array
Use a hash table to keep track of unique values
If a value is already in the hash table, remove it from the array
Q6. What are the basics of SQL?
SQL basics include querying databases, manipulating data, and managing database structures.
SQL stands for Structured Query Language
Used for querying databases to retrieve specific data
Can also be used to insert, update, and delete data in databases
Used for creating and modifying database structures like tables, indexes, and views
Q7. What are the basics of Java
Java is a popular programming language known for its platform independence and object-oriented approach.
Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)
It is object-oriented, allowing for the creation of reusable code through classes and objects
Java uses a syntax similar to C++, making it easy for programmers to learn if they are familiar with C-based languages
Q8. Pillars of the python
The pillars of Python refer to the core principles that guide the design and development of the Python programming language.
Readability counts: Python emphasizes code readability and simplicity, making it easier for developers to write and maintain code.
Explicit is better than implicit: Python encourages clear and explicit code over ambiguity and complexity.
Simple is better than complex: Python promotes simplicity and straightforward solutions to problems.
There should be one-...read more
Q9. Find 2nd highest salary
To find the 2nd highest salary, use a subquery to select the max salary that is not the highest.
Use a subquery to find the maximum salary that is not the highest
Select the maximum salary from the table where the salary is less than the highest salary
Order the results in descending order and limit the result to the second row
Q10. What are the types of trends?
There are various types of trends in UI/UX design.
Visual trends (e.g. flat design, material design)
Interaction trends (e.g. microinteractions, chatbots)
Layout trends (e.g. card-based design, asymmetrical layouts)
Typography trends (e.g. bold and large fonts, custom typography)
Color trends (e.g. gradients, duotones)
Animation trends (e.g. motion graphics, 3D animations)
Q11. how can we use javascript with css and html

Good UX design results in products that are easy to use and meet user goals
Examples of good UX design include the iPhone, Airbnb, and Google Maps
Q13. dsa questin base on dynamic pattern
Dynamic programming is a method for solving complex problems by breaking them down into simpler subproblems.
Identify the optimal substructure and overlapping subproblems in the problem
Use memoization or tabulation to store and reuse solutions to subproblems
Examples: Fibonacci sequence, Longest Common Subsequence, Knapsack problem
Q14. what is the use of devops
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle and provide continuous delivery.
DevOps aims to automate and integrate the processes between software development and IT teams to build, test, and release software more quickly and reliably.
It involves collaboration, communication, and integration of tools to streamline the development and deployment of software.
DevOps helps organizations ...read more
Q15. What is Polymorphism?
Polymorphism is the ability of an object to take on many forms.
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: Animal superclass with Dog and Cat subclasses. Both Dog and Cat can be treated as Animals.
Q16. Explain oops concepts
OOPs concepts are fundamental principles in object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class. Example: Animal class can be inherited by Dog class.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Using private variables and public methods in a class.
Polymorphism: Ability of a single function or method to...read more
Q17. hoistintg in javascript
Hoisting in JavaScript refers to the behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable declarations are hoisted but not their initializations.
Function declarations are fully hoisted, meaning they can be called before they are declared.
Hoisting can lead to unexpected behavior if not understood properly.
