Data refers to facts, statistics, or information collected for analysis or reference.
Data is raw, unprocessed information.
It can be in the form of numbers, text, images, or any other format.
Examples include customer names, product prices, and sales figures.
Data can be structured (organized in a specific way) or unstructured (not organized).
Preprocessed data is data that has been cleaned, transformed, and organized for analysis or modeling.
Preprocessed data is often used in machine learning and data analysis to improve the accuracy and efficiency of models.
Common preprocessing steps include removing missing values, scaling features, and encoding categorical variables.
Examples of preprocessing techniques include normalization, standardization, one-hot enco
Info refers to data or knowledge that provides details or context about a specific topic or subject.
Info can be in the form of facts, statistics, or explanations.
It helps to understand a topic better or make informed decisions.
Examples of info include news articles, research papers, and educational resources.
Use SQL INSERT INTO SELECT statement to copy data from 2 tables and paste into a 3rd table.
Use INSERT INTO SELECT statement to copy data from 2 tables and paste into a 3rd table.
Specify the columns you want to copy from each table in the SELECT statement.
Make sure the columns in the SELECT statement match the columns in the 3rd table where you are pasting the data.
Reverse a string using any programming language
Use built-in functions like reverse() or slice() in languages like Python or JavaScript
Iterate through the string in reverse order and append each character to a new string
Use a stack data structure to push each character onto the stack and then pop them off to reverse the string

I rate myself 4 out of 5 in IT skills.
Proficient in programming languages such as Java, Python, and C++
Experienced in software development and debugging
Familiar with database management systems like MySQL and MongoDB
The four pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Inheritance: Allows a class to inherit properties and behavior from another class.
Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hides the complex implementation details and only shows the necessary features.
Print a specific pattern using loops
Use nested loops to print the desired pattern
Increment the number of characters printed in each row
Adjust the spacing to create the desired pattern
Static keyword is used in programming languages to declare variables, functions, or classes that are shared among all instances of a class or are only accessible within a specific scope.
Static variables retain their values between function calls
Static functions can only be called within the same file
Static classes cannot be instantiated and are used for grouping related methods and properties
I applied via Naukri.com and was interviewed in Jun 2024. There were 3 interview rounds.
apply, call, and bind are methods used to manipulate the context of a function in JavaScript.
apply() - calls a function with a given 'this' value and arguments provided as an array
call() - calls a function with a given 'this' value and arguments provided individually
bind() - creates a new function that, when called, has its 'this' keyword set to the provided value

I applied via campus placement at ABES Engineering College, Ghaziabad and was interviewed in Feb 2024. There were 4 interview rounds.
They have 4 round total. In first round they take online Aptitide test in college labs.Aptitude topics are (Mcq on C,Java,C++ and quantitative aptitude,logical e.t.c), All rounds are Elimination round.
In 2nd Round they take coding test on your college systems.They don't have their plateform.You have to write code on any offline compiler.Coding question are based on linkedlist,array,string,hashmap only.They give 3 coding question if you solve 2 , you will be selected for next round.
Ques1: given an array of string and their frequency , find the string which have duplicate frequency.
Ques2: Find if an array contain any non empty subarray of zero sum in an array.
Ques 3: Find the string is isomorphic or Not.
Static keyword is used to create class-level variables and methods, while final keyword is used to make a variable constant.
Static keyword is used to create variables and methods that belong to the class itself, rather than to any specific instance of the class.
Final keyword is used to make a variable constant and cannot be changed once it has been assigned a value.
Static variables are shared among all instances of a c...
HashMap internally uses an array of linked lists to store key-value pairs, with keys hashed to determine the index.
HashMap uses hashing to determine the index of key-value pairs in the array.
Each index in the array can store multiple key-value pairs in a linked list.
When a key is inserted, its hash code is used to find the appropriate index in the array.
If multiple keys hash to the same index, they are stored in a link...
Detect cycle in a linked list
Use two pointers approach - slow and fast pointers
If there is a cycle, the fast pointer will eventually catch up to the slow pointer
Check if the fast and slow pointers meet at some point to detect the cycle

Polymorphism allows objects of different classes to be treated as objects of a common superclass. Interface is a contract that defines a set of methods that a class must implement.
Polymorphism allows for flexibility in programming by enabling a single interface to be used to represent multiple types of objects
Interfaces in Java are similar to abstract classes, but they cannot contain any implementation code

ACID properties ensure data integrity in DBMS: Atomicity, Consistency, Isolation, Durability.
Atomicity ensures that all operations in a transaction are completed successfully or none at all.
Consistency ensures that the database remains in a consistent state before and after the transaction.
Isolation ensures that multiple transactions can be executed concurrently without affecting each other.
Durability ensures that once...
