In this article we will see how to find a pair of items in an array which has sum equals to a specific target number. So we will use JavaScript to implement the algorithm. Understanding the Problem The problem at hand is to find the pair of numbers in the array whose sum is equal to the given target value. And the target value should also be there in the array. Or we can say that we have to identify pairs (a, b) where a + b = c and c is also present in the array. ... Read More
In the given problem statement we are presented with a digit and our task is to split it into individual digits with the help of Javascript. So we can convert the given number into a string and then we can use it in string manipulation techniques to get the desired result. Understanding the Problem In Javascript, it is very common to manipulate numbers at the individual digit level. So this is a common task to split the given number into its constituent digits. And extract it for further process or analysis. Logic for the given Problem ... Read More
In the given problem statement we are presented with two arrays which contain integer values. So our aim is to find the non negative set subtraction from the two arrays. And implement the solution in Javascript. We can perform this task using the Set object and forEach method. What are the Set object and forEach method in Javascript ? Set object in Javascript The Set is an object in Javascript which is a built in data Structure introduced in ES6. This allows us to store the unique values of any type. The values can be primitive values or ... Read More
In the given problem statement our aim is to find the maximum sum of n consecutive items of array with the help of Javascript functionalities. So for solving this problem we will use basic Javascript functionalities and produce the maximum sum. Understanding the Problem The problem at hand is to find the maximum sum of n consecutive items in the array. This process will involve identifying a continuous subarray of length n within the given array which has the highest possible sum. For example suppose we have an array as [1, 2, 4, 7, 3, 5] so that ... Read More
Overview Dynamic websites are the website on which a user sends the request from the client side to the server side and the data is rendered in the backend, as PHP is a server side scripting language so it plays the main role while creating dynamic websites. Some of the dynamic websites are like website admin panels or the searched content for the specific users.

As in a human being the bony skeleton plays the role of the HTML and the properties of the human being such as color, height, size and many other properties plays the role of CSS. So when a user requests a page from the server, the server sends the response ... Read More

This habit will make your code bug free and will also help you to create a new, creative and a faster way to build an application. Quality of a good developer A good developer ... Read More
XOR, or exclusive OR, is a boolean logic operation which is used in generating parity bits for error checking, fault tolerance, etc. Various symbols are used to represent this operation: ^, ⊕, ⊻, etc. XOR Logic The XOR operation is only true if the two arguments are different. This means that the XOR of the same bits is 0, and that of different bits is 1. Same bits − 0 ^ 0 = 0 1 ^ 1 = 0 Different bits − 0 ^ 1 = 1 1 ^ 0 = 1 Problem Statement Given two numbers, a and b, ...

When the minute hand moves from 12 to 12 in one hour, the hour hand also moves from the previous hour to the next. Hence, every hour, the minute hand and the hour hand coincide once. Problem Statement Given an input hour, find the time in minutes when the hour hand and the minute hand coincide within the next hour. Examples Input − Hour = 4 Output − Coinciding time: 240/11 minutes. We will discuss the explanation further with the approach. Input − Hour = 5 Output − Coinciding time: 300/11 minutes. Explanation and the Approach ... Read More
5, 55, 555, ... is a series that can be derived from geometric progression and, thus, computed with the help of GP formulae. Geometric progression is a type of series in which each succeeding term is the product of some specific term (ratio) with the preceding term. We will utilize the knowledge of GP, to find the sum of the given series. Problem Statement Given a number n, find the sum of the series 5+5+555+... up to n terms. Examples Input − N = 3 Output − 595 Explanation 5 + 5 + 555 = 595. ... Read More
