Read MoreHow to get almost increasing sequence of integers in JavaScript ?
In the given problem statement we have to get an almost increasing sequence of integers with the help of Javascript functionalities. So we will use some basic functionalities of mathematics and Javascript. Understanding the problem The problem at hand is to generate an almost increasing series of integers in Javascript. So the almost increasing sequence is a sequence in which every item is greater than or equal to the previous item. In other terms we will say it allows for a single item in the sequence where an item is smaller than the previous item. So the resultant ...
Read MoreGroup a sorted array based on the difference between current and previous elements in JavaScript
In the given problem statement we have to group a sorted array based on the difference between the current and previous elements with the help of Javascript functionalities. To group a sorted array based on the difference between the current and previous items we can iterate over the array and create a new array of groups. Understanding the Problem Statement The above problem statement states that we have to find out the group of elements based on the difference between the current and previous elements in the array. As we have given a sorted array so we need ...
Read MoreGiven an array of integers return positives, whose equivalent negatives present in it in JavaScript
In the given problem statement we are presented with an array which contains positive and negative values. So our task is to keep the positive once and filter out the negative numbers from the array. And implement the solution in Javascript. Understanding the Problem We will be given an array of integer numbers and we need to find the positive integers which have their respective negative integers present in the array. For example suppose we have an array of integers like [7, -7, 8, -8, 9, -9], in this array we can see that their is some positive ...

So basically we have to create an algorithm for finding the century number corresponding to the given year. So first understand what the century number is! A century represents a period of 100 years, beginning from the year 1. For example, the 20th century ...
Read MoreGenerating desired combinations in JavaScript
In the given problem statement we have to generate the desired combinations of the given inputs. And program the solution with the help of Javascript programming . Understanding the Problem In this problem, we will be given integers from 1 to 9. Each combination should be a unique collection of numbers. The function should identify all the possible combinations of size m that and these items with size m should have the sum of n. For example if the value of m is 3 and n is 6, then the combination should be [1, 2, 3]. ...
Read MoreFunction for counting frequency of space separated elements in JavaScript
In this problem statement, our target is to create a function for counting frequency of space separated elements with the help of Javascript functionalities. Understanding the Problem The given problem is stating that we have given a space separated elements and our task is to count the frequency of space separated items. So we will provide some strings with some space separated items and assign a result array to see the counts of the frequency of such items. For example if we have a string with space separated items like “Car, Bike, Car, Bicycle, Bike”, in this ...
Read MoreFinding the smallest multiple in JavaScript
In the given problem statement we have to find the smallest multiple of the given numbers with the help of Javascript functionalities. So we will use loops to iterate through and check the multiples of the given numbers. Understanding the Problem The problem at hand is to find the smallest multiple of the given number in Javascript. The multiple of a number is a number that can be divided evenly by that number. To solve the problem we will use a loop and iterate over the numbers until we find the smallest multiple which is divisible by all ...
Read MoreFinding the nth prime number in JavaScript
In the given problem statement our task is to find the nth prime number with the help of Javascript functionalities. So we will use two functions to solve this problem. Understanding the Problem The problem at hand is to find the nth prime number using the Javascript programming. So the prime number is a positive integer number which is greater than 1 and which has no positive divisors other than 1 and the number itself. The task is to create a Javascript function which takes an input n. Here n represents the position of the prime number which ...
Read MoreFinding the largest prime factor of a number in JavaScript
In the given problem statement we have to find the largest prime factor of a number with the help of Javascript functionalities. So we will solve this problem with the help of basic functionalities of Javascript. Understanding the Problem The problem at hand is to find the largest prime factor of a given input number. So the prime factor of a number is the prime number which can divide the given number without leaving the remainder. Our task is to find the largest prime factor which is the prime factor with the highest value. For example let's say ...
