The equilibrium sum of the given array is the sum at a particular point or index of the array after which the subarray has the total sum equal to the sum of the subarray starting from the 0th index to the current index (including the current index). We will see the examples and the code implementations in JavaScrript with the different approaches. Introduction to Problem We are given a single array in which we have to find a point from which the total sum of the elements that are present on the left side (including the current index element) is ...

In this program, we are given an array of integers of even length as we know here we have to make groups of two. We have from that groups using elements of an array, we have to choose two groups among them in order to find the maximum difference between that two groups and we have to return that maximum difference which is going to see in the article below. Introduction to Problem In the given problem we have to find the Maximum difference between groups of size two. It means we have given an array of even length and ... Read More

In this tutorial, we will discuss two approaches to finding the intersection point of two linked lists in JavaScript. The first approach involves using the loops, and the second approach involves using the difference of nodes technique which works in the linear time. We will be given two linked lists that are not sorted. Note that there is another version of this problem in which we are given a sorted pair of linked lists and have to find the intersection. We have to find the elements after which all the elements in both linked lists are the same. We will ... Read More

Testing JavaScript code automatically can help us to ensure that our code works as intended and catches any bugs or errors it contains. In this article, you will learn about how we can test JavaScript code automatically. Several types of tests are there which can be performed on JavaScript. Unit Tests In this testing we test all the function unit; modules or components which JavaScript program contain. The goal of unit testing is to verify that the smallest possible pieces of code work as expected. In JavaScript, unit testing can be performed using frameworks such as Jest or Mocha. Integration ...
