MVC is a design pattern used in .NET development, while .NET lifecycle refers to the stages of a .NET application's execution.
MVC is a design pattern that separates an application into three main components: Model, View, and Controller.
.NET lifecycle refers to the stages of a .NET application's execution, including initialization, execution, and termination.
MVC helps in achieving separation of concerns and making the c...
Dispose is used to release unmanaged resources immediately, while Finalize is used for cleanup operations before an object is destroyed by the garbage collector.
Dispose is called explicitly by the developer, while Finalize is called by the garbage collector.
Dispose should be implemented in classes that directly interact with unmanaged resources.
Finalize should be implemented in classes that need to release resources be...
DOM sanitizer in Angular is used to sanitize untrusted HTML to prevent XSS attacks.
DOM sanitizer is used to sanitize HTML content before rendering it in Angular templates.
It helps prevent Cross-Site Scripting (XSS) attacks by removing potentially harmful content.
Angular provides a built-in DomSanitizer service for sanitizing HTML content.
Example: Using DomSanitizer in Angular template to sanitize a URL before rendering
I use Ngrx for state management in my current project by defining actions, reducers, effects, and selectors.
Define actions to describe user events or interactions
Create reducers to specify how state should change in response to actions
Implement effects to manage side effects like API calls
Use selectors to retrieve specific pieces of state for components
Stored procedures are precompiled SQL queries stored in the database, while functions are reusable code blocks that return a value.
Stored procedures are used for performing specific tasks or operations on the database.
Functions are used to encapsulate logic and can be called within SQL queries or other functions.
Stored procedures can have input and output parameters, while functions always return a value.
Stored procedu...
Model binder in MVC is used to map data from HTTP requests to action method parameters in controllers.
Model binder maps form data, query string parameters, and route data to action method parameters in MVC controllers.
It helps in simplifying the process of extracting data from HTTP requests.
Model binder can be customized by creating custom model binders to handle complex data binding scenarios.
Yes, the transaction will be rolled back if the innermost stored procedure throws an error.
If an error occurs in the innermost stored procedure, it will cause the entire transaction to be rolled back.
This ensures that the database remains in a consistent state.
Rolling back the transaction means that any changes made by the stored procedures within the transaction will be undone.
NgOnInit is a lifecycle hook in Angular that is called after the component has been initialized, while the constructor is a TypeScript feature used to initialize class properties.
NgOnInit is specific to Angular components, while constructor is a general TypeScript feature.
NgOnInit is used for initialization logic that relies on Angular's view and input bindings being initialized, while constructor is used for basic ini...
zone.js is a library for managing asynchronous operations in Angular applications.
zone.js helps in tracking asynchronous operations and their execution context in Angular applications.
It provides hooks for intercepting asynchronous tasks like setTimeout, setInterval, and promises.
zone.js can be used for profiling, debugging, and error handling in Angular applications.
Use a query with GROUP BY and HAVING clause to identify and remove duplicates from a table.
Use GROUP BY to group rows with the same values
Use HAVING COUNT(*) > 1 to identify duplicates
Use DELETE statement to remove duplicates

Round duration - 60 minutes
Round difficulty - Easy
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

Count the number of even or odd numbers in a range of an array based on given queries.
Create an array to store the input numbers.
Iterate through the queries and update or count even/odd numbers based on the query type.
Output the count of even or odd numbers for each query of type 1 or 2.
Round duration - 30 minutes
