Integer compare() Method The compare() method in the Integer class is a part of the Java interface and is used to compare two integers. It provides a way to compare two Integer objects or primitive int values and determine their relative ordering. This method is particularly useful when sorting or working with collections that involve integer values. Syntax public static int compare(int x, int y);Where − x: The first integer to be compared. y: The second integer to be compared. Return Value The compare() method returns an integer value that ...

Problem Description In this problem, we are given an array that contains all unique elements except one element which is present exactly two times in the array. We have to return that element which is present two times in the array. In this article, we are going to learn how we can find duplicates in an array of N+1 integers in C++. Example Input: array = {1, 3, 4, 2, 2} Output: 2 Explanation: 2 is the only element in the array that occurs two times. Approaches to Find Duplicate Element in an Array ... Read More
Cartesian-coordinate System and Quadrants The cartesian-coordinate system is divided into four Quadrants: Quadrant I, Quadrant II, Quadrant III, and Quadrant IV. In this article, we are going to learn how we can determine the quadrant in which given points i.e., x and y, lie in C#. Problem Description We are given the position of a point (x, y), and we have to determine in which quadrant the given point lies in C#. Example 1 Input: (-6, 4) Output: Quadrant II Example 2 Input: (1, 2) ... Read More
Problem Description In this problem, we are given coordinate points of a 2-dimensional plane and a 3-dimensional plane, and we have to find the distance between these two points. In this article, we are going to discuss how we can find the distance between two points in C++. Approaches to Calculate Distance Between Two Points To solve this problem, here are the two approaches that can you use: Using 2D Coordinates Using 3D Coordinates Using 2D Coordinates In this approach, we use the direct distance formula to calculate ...

Problem Description We are given a number and we have to check whether it is an automorphic number or not. An Automorphic Number is a number whose square ends with the number itself. For example, 52 = 25 (ends with 5), so 5 is an Automorphic Number. In this article, we will learn how to check whether a given number is an automorphic number or not in C. Examples Consider the following examples, which ... Read More
In this article, we will learn to build a JavaScript function that calculates the complementary color for a given hex color code. In web development working with colors and their relationships is an essential aspect of design and user interface. One of the concepts that designers often use is complementary colors—colors that are opposite each other on the color wheel, providing contrast and enhancing the visual appeal.You can try our Online Color Picker Tool to create new colors. Understanding Complementary Colors The following is the knowledge through which we understand complementary colors − Complementary ... Read More
In this article, we will learn array sorting by level in JavaScript, creating a hierarchical tree structure from a flat array is a common challenge when dealing with relational data. This is a common task when dealing with hierarchical data, such as organizational charts, category trees, or file systems, where relationships like parent-child need to be represented. Problem Statement We have an array of objects representing nodes with _id, level, and parentId properties. Our goal is to transform this array into a tree structure where nodes are nested as children under their respective parents. The elements with the highest level ... Read More

Using git showThe git show command is one of the most straightforward ways to list file changes in a commit. ... Read More
When using Tailwind CSS in a Next.js project, it's common to apply utility classes for styling. However, if you're using CSS Modules, it can be difficult because the styles are scoped locally. The @apply directive in Tailwind allows you to combine multiple utility classes into one rule, making it easier to use Tailwind with CSS Modules. Our goal is to show you how to set up Tailwind CSS with CSS Modules in a Next.js project and use the @apply directive properly. Approaches Here, we will cover two approaches for using Tailwind's @apply inside CSS Modules in a Next.js project. ... Read More
