Read MoreGet average of every group of n elements in an array JavaScript
In the given problem, we have to find out the average of every group of n elements in the array. If there are m elements in the array, then calculate the average of every group and show the result in array form. Understanding the Problem Suppose we have 6 elements in the array and make a group of 2 elements. Now calculate the average of every group individually. Now that we have their average values, we can combine them into a single array. To implement this problem we have used reduce(), push(), and slice(). These ...
Read MoreCounting duplicates and aggregating array of objects in JavaScript
The Given problem is stating to count the duplicates of array elements and then aggregating objects in a new array. Understanding the Problem Problem statement is saying to identify the duplicate elements from an array and make a single array of those objects stating the counts. To solve this question we will use brute force technique with the help of for loops. What is an Aggregating Array of Objects? Aggregation in an array refers to combining down several objects in a new array as an output. We have to check if the aggregate of objects ...
Read MoreAdding binary strings together JavaScript
The problem is stating that we have to add two binary strings. Binary strings are a sequence of bytes. To add them in javascript, we will first convert them to decimal and calculate the sum. After adding those decimal numbers, we will convert it again into binary strings and print the output. What are Binary Strings? Binary numbers or binary strings are sequences of bytes in base 2. It is basically a combination of 0 and 1 to represent any number. While binary addition is one of the operations of mathematics to perform on binary strings. Binary addition ...
Read MoreSum of even Fibonacci terms in JavaScript
In the given problem statement we have to calculate the sum of even fibonacci numbers with the help of Javascript functionalities. So for solving this task we will use basic functionalities of the language. Understanding the Problem The problem at hand is to calculate the sum of even fibonacci numbers or items up to the given limit of the fibonacci number. As you may know, the fibonacci sequence is a series of numbers in which every number is the sum of the two previous numbers. The series usually starts from 0 and 1. So in this problem our ...
Read MoreSum of all prime numbers in JavaScript
In the given problem statement we have to compute the sum of all the prime numbers with the help of Javascript functionalities. So for calculating the sum we will set the upper limit of primes numbers. Understanding the Problem The problem is to calculate the sum of all the prime numbers up to a given limit. So the prime number is a positive integer which is greater than 1 and also these numbers do not have any divisors other than 1 and itself. For example we have a limit of the primes is 10, so the prime numbers ...

Understanding the Problem The problem says to sort the given integer number without using the string and array method in Javascript. The question arises about sorting the integer that means we have to array its digits in ascending or descending order. For example suppose we have an integer number as 784521, so ...
Read MoreSorting according to weights of numbers in JavaScript
In this problem statement, our target is to sort the given array of numbers according to the weights of numbers with the help of Javascript. At the beginning we will write a function that calculates the weights of the numbers and then sort them with another function. Understanding the Problem We have to sort the provided numbers according to their weights. As a result we will have an array of numbers. A weight of the number is defined as the sum of its own digits. For example: suppose we have an array like [19, 11, 12, 15]. We ...
Read MoreSort an integer array, keeping first in place in JavaScript
In the given problem statement we have to sort the given integer array but we have to keep the first item in place and sort the remaining items with the help of Javascript functionalities. So we will use some predefined functions of Javascript to solve the problem. Understanding the Problem The problem at hand is to get the sorted array of integer numbers in Javascript and the main operation in this task is to keep the first item intact in its original position. Or we can say we have to rearrange the items in the array so that ...
Read MoreSmallest number that is divisible by first n numbers in JavaScript
In the above problem statement our task is to find the smallest number that is divisible by the first n numbers with the help of Javascript functionalities. So Understanding the Problem The problem at hand is to find the smallest number which is evenly divisible by the first n numbers. Or we can say that we have to look for a lowest number that can be divided by each of the numbers from 1 to n without any remainder. Logic for the given Problem For solving this problem we can use the concept of Least ...
