DI in .Net Core allows for loosely coupled and testable code.
Add services to the DI container in Startup.cs
Inject dependencies into classes using constructor injection
Use built-in DI or third-party libraries like Autofac
Configure lifetime of services with AddScoped, AddTransient, or AddSingleton
To call DI in controller, inject the required service in the constructor of the controller.
Add required service in ConfigureServices method of Startup.cs
Inject the service in the constructor of the controller
Use the service in the controller methods
Validation in MVC
Use data annotations for server-side validation
Use jQuery validation for client-side validation

Clustered indexes determine physical order of data, non-clustered indexes are separate structures.
Clustered indexes sort and store data rows in the table based on their key values.
Non-clustered indexes have a separate structure that includes the indexed columns and a pointer to the data row.
Tables can have only one clustered index, but multiple non-clustered indexes.
Clustered indexes are faster for retrieving large amo...
Query optimization in SQL
Use indexes to speed up queries
Avoid using SELECT *
Use JOINs instead of subqueries
Avoid using functions in WHERE clauses
Use EXPLAIN to analyze query performance
Transactions in SQL ensure data consistency and integrity during multiple operations.
Transactions group multiple SQL statements into a single unit of work.
They ensure that all statements are executed or none are executed.
They provide data consistency and integrity during multiple operations.
Transactions can be started with BEGIN TRANSACTION and committed with COMMIT or rolled back with ROLLBACK.
They are useful in situa...
Inner join returns only matching records while outer join returns all records from both tables.
Inner join is used to retrieve records that have matching values in both tables.
Outer join is used to retrieve all records from both tables, even if there are no matching values.
Left outer join returns all records from the left table and matching records from the right table.
Right outer join returns all records from the right

This was an easy round which went really smooth.
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10
2 3 5 7
N = 20
Implement a function to return all prime numbers less than or equal to a given positive integer N.
Create a function that takes a positive integer N as input
Iterate from 2 to N and check if each number is prime
Use a helper function to determine if a number is prime
Return an array of all prime numbers less than or equal to N
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i

Implement a function to multiply two sparse matrices and return the resulting matrix.
Create a function that takes two sparse matrices as input and returns the resulting matrix after multiplication
Iterate through the non-zero elements of the matrices to perform the multiplication efficiently
Handle the edge cases such as empty matrices or matrices with all zero elements
Ensure the dimensions of the matrices are compatible
