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
Python's implementation of a data structure known more commonly as an associative array is a dictionary. A dictionary is made up of a group of key-value pairs. Each key-value combination corresponds to a key and its corresponding value. In this article, we will learn how to concatenate all keys which have similar values in python. Methods Used The following are the various methods to accomplish this task: Using defaultdict() and join() functions Using dictionary comprehension, groupby() and join() functions Example Assume we have taken an input dictionary. We will now concatenate all the keys ... 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
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 this problem we will understand how to get a single array from multiple arrays and different ways to solve this problem. We will use three methods to solve this problem: the first method is with the help of the spread operator, second concat method and finally last method using push with the spread operator. Understanding the problem We have given two or more arrays and we have to concatenate them in a single array. There can be many arrays given and after concatenating them it should appear as a single array. Let’s understand with ... Read More
In the given problem statement we have to group the given data month wise. In simple terms the data should be in sorted form after grouping them month wise. For example we have years and months given in data so it should be visible in the order from January to December. As we know that Arrays are the data structures template to store data. And we can manipulate that data as per our requirement. It can store a collection of items in a single array, and has many operations to perform like adding an element, deleting an element, ...

In python an array(list) of comma-separated values (items) enclosed in square brackets is one of the most flexible data types available in Python. The fact that a list's elements do not have to be of the same type is important. In this article, we will learn a python program to check whether a number formed by combining all elements of the array is a palindrome. Methods Used The following are the various methods to accomplish this task: Using map() & join() functions Using type casting & string concatenation Using str(), list(), extend(), join() and reverse() functions Example ...

Python's implementation of a data structure known more commonly as an associative array is a dictionary. A dictionary is made up of a group of key-value pairs. Each key-value combination corresponds to a key and its corresponding value. In this article, we will learn a python program to convert URL parameters to dictionary items. Methods Used The following are the various methods to accomplish this task − Using urllib.parse.parse_qs() function Using setdefault() and re.findall() functions Using split() function Example Assuming we have taken an input string with URL parameters, we convert this query string to the ...

Python has internal functions lie count, counter and operator functions that can be used for printing all the repeated digits present in a number that too in sorted order. The following example will help you understand the concept more clearly. Example Assume we have taken an input string. We will now print all repeating/duplicate digits present in a given input number in sorted order using the above methods. Input inputNum = 5322789124199 Output 1 2 9 In the above input number, 2, 1, and 9 are repeated digits. So these digits are sorted in ascending ... Read More
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 More
