LINQ (Language Integrated Query) is a Microsoft technology that allows querying data from different sources using a common syntax.
LINQ provides a unified way to query data from different sources such as databases, XML documents, and collections.
It allows developers to write queries using a common syntax regardless of the data source.
LINQ queries are strongly typed and can be checked at compile time.
Examples of LINQ pro...
ADO.NET is a data access technology used to connect applications to databases.
ADO.NET provides a set of classes to interact with databases.
It supports disconnected data architecture.
It uses Data Providers to connect to different databases.
It supports LINQ to SQL for querying databases.
Examples of Data Providers are SQL Server, Oracle, MySQL, etc.

Procedures and triggers are database objects used to automate tasks and enforce rules.
Procedures are a set of SQL statements that can be executed repeatedly.
Triggers are special types of procedures that are automatically executed in response to certain events.
Triggers can be used to enforce business rules, audit changes, or replicate data.
Procedures and triggers can be written in various programming languages such as S
An abstract class is a class that cannot be instantiated and is used as a base class for other classes.
An abstract class can have abstract and non-abstract methods.
Abstract methods have no implementation and must be implemented by the derived class.
An abstract class can have constructors and fields.
An abstract class can be used to define a common interface for a group of related classes.
Example: Animal is an abstract c
Encapsulation is hiding implementation details while abstraction is showing only necessary details.
Encapsulation is achieved through access modifiers like private, protected, and public.
Abstraction is achieved through abstract classes and interfaces.
Encapsulation provides data security and prevents unauthorized access.
Abstraction helps in reducing complexity and improves maintainability.
Example of encapsulation: Class ...
Singleton design pattern restricts the instantiation of a class to a single instance.
Ensures only one instance of a class exists
Provides a global point of access to that instance
Used when only one object is needed to coordinate actions across the system
Example: Database connection manager

In this round, the interviewer asked me 2 coding questions , the first one was related to Simple Hashing and the second one was to implement Kadane's Algorithm. I coded both the solutions in the given time and at the end was also asked some questions revolving around OOPS and C#.
Given an array of integers ARR
of length N
and an integer Target
, your task is to return all pairs of elements such that they add up to the Target
.
The first line ...
The task is to find all pairs of elements in an array that add up to a given target.
Iterate through the array and for each element, check if the target minus the element exists in a hash set.
If it exists, add the pair to the result. If not, add the element to the hash set.
Handle cases where the same element is used twice in a pair or no pair is found.
Time complexity can be optimized to O(N) using a hash set to store el
Given an array or list ARR

integers, your objective is to compute the maximum possible sum obtainable from a non-empty subarray (a contiguous sequence) within thi...
Find the maximum sum of a subarray within an array of integers.
Iterate through the array and keep track of the maximum sum of subarrays encountered so far.
At each index, decide whether to include the current element in the subarray or start a new subarray.
Update the maximum sum if a new maximum is found.
Example: For input [-2, 1, -3, 4, -1], the maximum subarray sum is 4.
Data encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
Data encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing direct access from outside the class.
Encapsulation also helps in achieving data abstraction, where only relevant information is exposed to the outside world.
Examp...
Method overloading in C# allows multiple methods with the same name but different parameters.
Method overloading can be achieved by changing the number of parameters in a method.
Method overloading can be achieved by changing the data type of parameters in a method.
Method overloading can be achieved by changing the order of parameters in a method.

This round was preety much mixed and had questions from LINQ , .NET framework, DBMS, OOPS and Design Patterns.
LINQ (Language Integrated Query) is a feature in C# that provides a consistent way to query data sources.
LINQ allows for querying data from different sources like databases, collections, XML, etc.
Advantages of using LINQ in a Dataset include improved readability, type safety, and easier data manipulation.
LINQ queries are executed at compile time, providing better performance compared to traditional methods.
Example: var...
LINQ is a query language in C# for querying data from different data sources, while Stored Procedures are precompiled SQL queries stored in a database.
LINQ is used to query data from different data sources like collections, databases, XML, etc.
Stored Procedures are precompiled SQL queries stored in a database for reuse.
LINQ queries are written in C# code, while Stored Procedures are written in SQL.
LINQ provides type sa...
An Expression Tree in LINQ represents code as data structure, allowing queries to be manipulated and executed dynamically.
Expression Trees are used to represent lambda expressions in a tree-like data structure.
They allow LINQ queries to be translated into a format that can be analyzed and executed at runtime.
Expression Trees can be inspected and modified programmatically, enabling dynamic query generation.
Example: var ...
Triggers are automatically executed in response to certain events, while procedures are manually executed by users.
Triggers are automatically invoked in response to data manipulation events, such as INSERT, UPDATE, DELETE.
Procedures are stored sets of SQL statements that can be executed manually by users.
Triggers are defined to execute in response to a specific event on a specific table.
Procedures can be called explici...
Abstraction is hiding complex implementation details, while data encapsulation is bundling data and methods together in a class.
Abstraction allows us to focus on the essential features of an object while hiding unnecessary details.
Data encapsulation restricts access to some of an object's components, protecting the integrity of the data.
Abstraction and data encapsulation help in achieving modularity and reusability in ...
Types of design patterns in Java include creational, structural, and behavioral patterns.
Creational patterns focus on object creation mechanisms, such as Singleton, Factory, and Builder patterns.
Structural patterns deal with object composition, such as Adapter, Decorator, and Proxy patterns.
Behavioral patterns focus on communication between objects, such as Observer, Strategy, and Template patterns.
