You’re given a triangular structure represented as an array of arrays, where each sub-array represents a row of numbers. Your task is to find the path from the top to the bottom of the triangle with the minimum sum. At each step, you’re allowed to move to an adjacent number in the row below. Adjacent […]

Binary search is a searching algorithm that finds the position of a target value within a sorted array or list. It is a divide-and-conquer algorithm that works by repeatedly dividing the search interval in half. Binary search is efficient for searching in large datasets because it reduces the search space by half with each comparison.
Today, we’re going to explore another sorting algorithm – the Selection Sort algorithm, implemented in JavaScript. Selection Sort is another simple sorting algorithm that sorts an array by repeatedly finding the minimum element from the unsorted part and putting it at the beginning. Like Bubble Sort algorithm, it’s not the most efficient for large datasets,
In this blog, we’re going to discuss sorting algorithm and learn about one of the simplest ones – the Bubble Sort algorithm. We’ll be implementing it in JavaScript, so if you’re a JavaScript enthusiast or just looking to brush up on your sorting algorithm knowledge, you’re in the right place. Keep reading to learn. So,
In this blog, we’re going to discuss how to implement queues in JavaScript. Specifically, we’ll cover two approaches: one using an array and another using a linked list. Implementing Queue using Array in JavaScript Let’s kick things off with a simple implementation using an array. In JavaScript, arrays are versatile data structures, making them suitable
In this blog, you’re going learn how to implement a Priority Queue in JavaScript. But what makes this tutorial even more interesting is that we’ll explore two different approaches using both an array and a linked list. We will be using object oriented programming approach using class and methods. So, keep reading to learn. A
In this blog, I will discuss various possible methods in JavaScript to insert an element at a specific index of array. Out of all the methods splice is my most favorite as it is the shortest to write. I have discussed other methods that will help you learn various array methods which might be useful

If you have been learning JavaScript , you might have came across == or === operator. It does not work as usual with arrays. Because arrays in JavaScript are objects. You won’t be able to find out if two arrays have equal elements at corresponding index values using these operators. In JavaScript, the == operator
In this blog we will discuss how to shuffle elements of array randomly using Fisher-Yates (Knuth) algorithm. We will also add some additional checks later to ensure we get shuffled array in any case i.e. if array has 2 or more elements. If array has one element or empty we can’t produce shuffled array. To

Nvm (node version manager) can be used to install different versions of node js and also you can easily switch between different versions of node js using Nvm. When creating Nodejs project different libraries require different version of Nodejs to work. In that case, we can easily switch to older or newer version of nodejs
