In this problem, we are given an array of integers, which may contain both negative and positive numbers. We have to find the average of all the negative numbers in the array. In this article, we are going to learn how we can find the average of all negative numbers in an array using JavaScript. Example 1 Input arr = [1, -3, 4, -2, -5]; Output -3.33 Explanation The negative numbers in the array are -3, -2, and -5. Their sum is -10, and the number of negative elements is 3. The average is: -10 / 3 = -3.33. ... Read More
Redux Thunk and Redux Saga are two famous middleware picks for controlling negative consequences in Redux packages. Although they use their own different techniques, each technology assist with asynchronous duties like API requests. Redux Saga offers an improved and flexible solution for complicated duties, whereas Redux Thunk is simpler to use and is more basic. This article will help you to decide that which one is suitable as per your needs by examining their features and differences. Redux Thunk You can create action creators that return a function rather than an action object by using Redux Thunk, a Redux middleware. ... Read More
In this article, we will learn to rank elements in arrays using JavaScript. Ranking elements in an array is common in various applications, such as sorting scores, evaluating performance, or analyzing data. What is Array Ranking? Array ranking involves assigning a rank to each element of an array based on its value, where the largest value gets the highest rank and the smallest value gets the lowest rank. This ranking can be extended to multiple arrays to analyze and compare data across different datasets. Problem Statement We are given multiple arrays of numbers. The task is to compute ranks for ...

In this article, we will learn to check if the browser tab page is focused and under use or not in JavaScript. This is mainly required to record the user’s inactivity time on the app and then take any action upon it if required. Use Cases for Monitoring Browser Tab Focus Following are the use cases for monitoring browser tab focus and user inactivity − Prevent sending the network request if the page is not being used by the user as this would reduce the traffic on the server. This would ... Read More
In this article, we will learn to calculate the adjacent elements product with the help of Javascript functionalities. This problem is often asked in coding interviews or algorithm challenges, and it tests one's understanding of array manipulation and performance optimization. Problem Statement Given an array of integers, your task is to return the largest product that can be obtained by multiplying any two adjacent numbers in the array. For example − Input [5, 1, 2, 3, 1] Output 6 The adjacent elements are (5, 1), (1, 2), (2, 3), and (3, 1). The largest product is 6 (from 2 * ... Read More
Problem Description In this problem, we are given a temperature value in Fahrenheit and we have to convert it to Celsius. This conversion is used in various real-world applications such as weather applications, scientific calculations, and data analysis. In this article, we are going to discuss, how we can convert Fahrenheit temperature to Celsius temperature in Python. Formula to Convert Fahrenheit to Celsius The formula for converting Fahrenheit to Celsius is: Celsius = (Fahrenheit - 32) / 1.8 Example 1 Input: Fahrenheit = 98.6 Output: Celsius = 37°C Explanation: The ...

Problem Description In this problem, we are given an unsorted array, and the task is to remove all duplicate elements from the array. The resulting array should only contain unique elements. In this article, we are going to explore different approaches to removing duplicates from an unsorted array in C++. Example 1 Input: array = {4, 3, 2, 4, 1, 3, 2} Output: {4, 3, 2, 1} Explanation: The duplicate elements (4, 3, 2) are removed, leaving only unique elements. Example 2 Input: array ... Read More

Functions are categorized bases on the presence or absences of arguments and whether they return a value. A user-defined function is one that is defined by the user when writing any program, as opposed to library functions that have predefined definitions. To meet specific requirements, the user must develop their own functions. Such functions must be properly defined by the user. A function is a block of code designed to perform a specific task. It is written once and can be reused multiple times as needed by the programmer. ... Read More
Unformatted input and output functions read a single input sent by the user and permit the display of the value as the output at the console. Unformatted input functions The unformatted input functions in the C programming language are used only for character data type or character string/array and cannot be used for any other datatype. These functions are used to read a single input from the user and this allows the user to display the value at the console. The getchar() Function This getchar() function reads only the first single character from the given keyboard that multiplies characters is typed ... Read More
