To visually demonstrate the completion of task or goal, we use the element. The max and value attributes show the progress made towards task completion. The element offers a visual representation of the completion status of task. It's typically displayed as a progress bar, indicating how much of a particular task has been completed. Here is the syntax for the tag in HTML − The element has both opening and closing tags. It is a new semantic element in HTML5. This progress bar id also used to display the progress of file being uploaded. ... Read More
Depth First Search (DFS) is an algorithm that traverses a graph, visiting all nodes before backtracking. It can also determine whether a path exists between two nodes. DFS begins at the root node and explores as far as possible along each branch before backtracking. DFS searches a graph or tree in a depth-wise manner. Algorithm Given below is an algorithm for the implementation of the Depth First Search (DFS) − Step 1 − Initially stack is empty. ... Read More
A calculator is a simple tool that helps us to calculate mathematical operations easily and quickly. A basic calculator can perform simple arithmetic operations like subtraction, addition, multiplication, and division. Begin by writing the C code to create a simple calculator. Then, follow the algorithm given below to write a C program. Algorithm Step 1: Declare variables Step 2: Enter any operator at runtime Step 3: Enter any two integer values at runtime Step 4: Apply switch case to select the operator: // case '+': result = num1 + num2; ...

To check if strings are rotations of each other or not, it means that two strings can be rotated to either the right or left direction to obtain the other string. In the right rotation characters of the string shift to their following index and for the zeroth index, it takes the character of the last index assuming the string is in a circle. Left rotation is similar to right rotation but in the opposite direction. In this article We are having two strings and we have to write a JavaScript program to check whether by rotating the characters of ... Read More
In this article, we will learn to reverse an array in Java. Reversing an array is a classic problem that helps understand essential concepts like data structures and in-place manipulation. This operation is commonly required in programming tasks, such as data transformations, algorithm implementations, and solving logical problems. Problem Statement Reversing an array involves rearranging its elements so that the first element becomes the last, the second becomes the second-to-last, and so on. Input int[] myArray = {23, 93, 56, 92, 39}; Output {39, 92, 56, 93, 23} Different Approaches Following are the two different approaches to reverse an array ... Read More
In this article, we will learn to create an array from JSON data in JavaScript. JSON is a widely used format for storing and exchanging data. A common use case involves extracting specific data from a JSON object or array and converting it into a separate array for further processing. What is JSON Data? JSON (JavaScript Object Notation) is a lightweight data format commonly used to store and exchange data between a server and a client. It represents data as key-value pairs and is easy for both humans and machines to read and write. In JavaScript, JSON objects or arrays can be ... Read More
The ResultSet interface in Java is used to retrieve data from a database in a tabular form. The isAfterLast() method is one of the navigation methods in the ResultSet that helps in checking the position of the cursor. Specifically, isAfterLast() checks whether the cursor is positioned after the last row of the result set. Method Definition The isAfterLast() method of the ResultSet interface is used to determine whether the cursor is after the end of the ResultSet.This method returns a boolean this value is true, if the cursor is after the end of the ResultSet else, it returns false. ...

What is Potential Energy? Potential energy is a type of stored energy stored by an object due to its position relative to other objects. It is an important concept in physics and is commonly calculated when studying objects in gravitational fields. In this tutorial, we are going to learn how to calculate the potential energy of an object in C++ if the mass and height are given. Formula for Calculating Potential Energy The formula for potential energy is as follows: Potential Energy = m × g × h Where:m is the mass of the object (in kilograms).g is the gravitational ...

Suppose we have an array of numbers called nums. We have to check whether it contains contiguous values or not. So, if the input is like nums = [6, 8, 3, 5, 4, 7], then the output will be true as the elements are 3, 4, 5, 6, 7, 8. Following is the sample example to check if elements of an array are consecutive. def solve(nums): if len(nums) < 1: return False min_val = min(nums) max_val = max(nums) if max_val - min_val ...

To find the length of a linked list in JavaScript, we need to count how many nodes are present. A linked list is made up of nodes, where each node contains data and a reference to the next node. The length is determined by starting at the head and counting each node until the end of the list. If the list is empty, the length should be 0. Our task is to write a JavaScript program that calculates the length of a linked list . In other words, we need to find out how many nodes are in the ... Read More
