The Given problem is trying to find three strictly increasing numbers with consecutive or non−consecutive numbers in an array with the help of javascript. Understanding the Problem Before starting to write algorithms and programmes for the given problem first we will understand the logic behind the problem. Consider a set of array with some random numbers in it. So JavaScript allows us to loop through an array and maintain track of the smallest and second−smallest values in order to find three strictly rising numbers. In this algorithm, We will discover three strictly growing integers if a third value ... Read More

The Given problem is stating to manipulate objects to group based on the output array object list with the help of javascript. Understanding the problem Before starting to write algorithms and programmes for the given problem first we will understand the logic behind the problem. Consider a set of objects that each represents a person and has details about that individual, such as person, age, and profession. We need to make a group of persons with the same profession. For instance, we wish to build an object whose properties each indicate a job and whose values are an array of ... Read More

This problem statement is saying to sort an array of objects based on the length of the nested arrays in it. For example if the first nested array has 3 elements and the second array has 2 elements then put the second array in first place and the first array at the second index. Understanding the problem Sorting an array of objects based on the size of a nested array is the task we have given. For example, let's say we have an array of objects in which each object has a name property and a hobbies property, ... Read More

In the given problem, we have to merge and group object properties with the help of javascript. In this article you will learn how to merge and group the same type of properties in javascript. Understanding the Problem We are required to create a javascript method that will take in one array of objects. The created function should group all the properties of all the objects that have a value for name property. For example: Input [ {name: 'Adi', age: 22, color:'Black'}, {name: 'Adi', weight: 40, height:6} , {name: 'Mack', ... Read More

As the problem stated, create a program for a unique sort in javascript. Basically we have to remove duplicate elements from an array. Understand the problem In this problem statement we need to eliminate the same or duplicated item from an array. For solving this kind of problem we can use some predefined methods of javascript. In this article you will be able to learn usage of forEach(), spread operator, set() method, filter() method and indexOf() methods. Lets understand this problem with an example. Array before sorting and with duplicates [535, 646, ... Read More

The problem statement says to merge duplicate elements and increase the count for every object present in the array and implement this program in javascript. Understanding the Problem To start coding we need to understand the basic functionality of the javascript functions. Predefined functions in JavaScript will complete half of our task. Merging and eliminating duplicates are the fundamental array optimization operations that can be performed. In this issue, we will define a count variable that will count how many entries there are in the array. We will go through each item in the array using the ... Read More

Given problem says to sort the given array of objects by two properties and create a program in javascript. Understanding the problem Let's have a deep understanding of the problem statement. You will be given an array of objects with key and value. As per the problem statement we need a sorted form of that array. To implement this problem we will first sort the first column of array and then second column of array. And then again arrange it in sorted form. As we understand arrays are basic data structures in computer science. Array can also ... Read More

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 More

In this problem, we have to group all the duplicate data in the array by making their subarray. After making the subarray we have to arrange them in a sorted order. This problem can be solved by searching techniques of data structures. Understanding the Problem So for solving this problem, we will use javascript’s reduce() method in two ways. The reduce method is an iterative method which uses a reducer function to iterate through all the items in the array. So by checking one by one we will keep track of all the elements and ... Read More
