The Working Programmer
Data science, data engineering, and data analysis are distinct but interconnected fields in the broader realm of data management and utilization. Here’s a breakdown of each: Data Science: Extracting insights and knowledge from data using statistical, mathematical, and programming techniques. Key Skills: Statistical analysis Responsibilities: Outcome: Provide actionable insights and recommendations based on […]
In SQL Server, the INSERT INTO and SELECT INTO statements are used for inserting data, but they serve different purposes and have distinct behaviors. Here’s a breakdown of the differences: INSERT INTO Syntax: INSERT INTO TargetTable (Column1, Column2) SELECT Column1, Column2 FROM SourceTable WHERE Condition; SELECT INTO Purpose: The SELECT INTO statement creates a new […]
Now that we have understood the basics of Tree & Binary Search Tree, the question is how we can read the data from each node, add a node, delete a node or search node (data) in a tree. To read data, we need to visit every node in the tree and this is called Tree Traversing. For […]
Trees are one of the most common data structure used. A tree is a non-linear data structure that is used to store data in a hierarchical manner. In this article we will discuss about tree, then learn about binary tree along with an implementation of binary tree — the Binary Search Tree also knows as […]

In this tutorial, we see how to update Nodejs & node package manager (npm) on our Raspberry Pi. To start, open the terminal on your Raspberry Pi. First we will get the latest system’s package list onto the Raspberry Pi using the following command: sudo apt update the we will install the latest packages available […]
In this tutorial, we will see how to use the rm, unlink, and rmdir commands to remove files and directories in Linus using Terminal (command line). Remove Files: To remove (or delete) a file on Linux using the command line, use either rm (remove) or unlink command. unlink command allows you to remove only a single file. rm command allows you to remove multiple files […]
Both are comparison operators. The difference between both the operators is that,“==” is used to compare values whereas, “ === “ is used to compare both value and types. Example: var a = 2; var b = “2”; (a == b) // Returns true since the value of both a and b is the same […]
Hoisting is a default behavior of JavaScript where all the variable and function declarations are moved on top. This means that irrespective of where the variables and functions are declared, they are moved on top of the scope. The scope can be both local and global. Below is the example:
Array are the simplest data structures, build into most programming languages and we use them to store list of items like list of numbers, string, objects and literally anything. These items get stored sequentially in memory. In many languages arrays are static – which means – when we allocate them we must specify their size […]
