Hacker Rank: 2D Array - DS Solution

I've been trying to solve the puzzles on lately. This post is just to solve the problem in Arrays section of Hacker Rank

I feel better to solve the problems though. It certainly improves some area in programming language.

As I'm a C# developer the problem is solved using C# as programming language.


And the solution is

Stack implementation using C#

A stack is a data structure.

And the definition as on Wikipedia:
In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed.
Data structures are so simple if you can understand everything in it. They are just another programs which are tied together with small pieces of implementation.

Intellisense in Visual Studio Code not working

I've noticed Visual Studio Code is not showing intellisense though I've done some settings in the editor.

Like someone in this post did few changes to his editor but it didn't worked either.

If you are facing the same problem then the cause is that OmniSharp is not installed with your visual studio code.

I didn't do any editor settings, but when I've opened the Visual Studio Code repeatedly I've noticed that OmniSharp package is installed now.

Once it is installed you'll see references to your method names as "0 references" as you can observe from above screenshot

If it is not installed you will only get basic intellisense support with Visual Studio Code (like if, for, while etc).

I doubt why this won't install as and when C# extension is installed. But after restarting the editor for multiple times I've noticed that OmniSharp is installed and the intellisense is working now.

Simple chat application using NodeJS and Socket.IO

Before we start creating a chat application with NodeJS, I'll just give you a brief idea of what NodeJS and Socket.IO is and what is does.

What is NodeJS ? NodeJS is a platform built for fast, scalable network applications. It is also used for creating real-time applications that interact with data related tasks.

Losing precision after multiplication in SQL Server

Yesterday I was doing a little multiplication operation in SQL SERVER. The computation involves multiplication of two decimal numbers. A point to note here is that I've to be very careful while performing the calculations because it's a monetary thing. So, Whatever the calculation made, it must be very accurate such that I shouldn't miss any fractions as it costs in MILLIONS. The scenario is that I've two numbers, after multiplying each other I'm losing the precision of the values. I've tried to check my database for any faulty data that caused the issue. But the data is absolutely fine.
