In this article, we'll learn to perform nCr (Combinations) in Java. In mathematics, nCr (combinations) is a crucial concept that helps determine how many ways you can choose r items from a set of n items, without considering the selection order. It is widely used in fields like probability, statistics, and combinatorics. What is nCr? The formula for calculating combinations (nCr) is − nCr = n! / (r! × (n - r)!) Where, n! = The factorial of n (product of all integers from 1 to n). r! = The factorial ... Read More
In this article, we will learn to create a BigDecimal from a string value in Java. The BigDecimal class in Java is highly versatile and often used for calculations requiring high precision, such as financial transactions or scientific computations. we'll explore two approaches to creating a BigDecimal from a string value, complete with examples. When to Use BigDecimal We can use the BigDecimal in the following conditions − When working with financial calculations requiring precision (e.g., currency operations). When handling scientific computations involving large or highly precise numbers. ... Read More
PyTorch is a very popular Python library used in machine learning. This library is developed by Facebook AI. This library provides robust tools for deep learning, neural networks, and tensor computations. Below are different approaches to Copying a Tensor in PyTorch. Using clone() function Using detach() method Using copy.deepcopy() method Using clone() function We use the clone() method to create a deep copy of a tensor. In deep copy, the original tensor and the copied tensor do not share memory. If we make changes in copied ... Read More
Problem Description Sometimes we need to compare two arrays in PHP to check if they are equal. Talking about equality, it means that the arrays have the same elements, in the same order, or even that their data types match. In this article, we will discuss how we can check if two arrays are equal or not in PHP. The following are different approaches to check If two arrays are equal in PHP - Brute Force Approach Using the == Operator Using array_diff() Method ... Read More

Combining Tailwind CSS with Sass using Webpack can be challenging. The main difficulty is configuring Webpack to handle both, making sure custom styles work well with Tailwind's utilities, and removing unused CSS in production to reduce the file size and improve performance. Our goal is to combine Tailwind and Sass in a simple way, using Tailwind's utilities for layout, applying custom styles with Sass, and removing unused CSS to optimize the final output Approaches to Combine Tailwind CSS with Sass using Webpack We'll cover some simple ways to combine Tailwind CSS with Sass using Webpack. Each method will help you ... Read More
In Java, a method is a block of code that performs a specific task. Methods can take zero or more parameters and can also return a value. When a method returns a value, we call it a method with a return type. A method without parameters but with a return type is a method that does not take any parameters but returns a value. This type of method is useful when we need to perform a specific task that does not require any input parameters, but we need to get a result from that task. First, let us get acquainted ...

A CSV is a comma-separated value that is stored in a file with the .csv extension. This allows the user to store data in a tabular or spreadsheet format. In this article, we will learn to convert the data of a CSV string to 2D array objects in JavaScript, where the first row of the string defines the file headers. We will be first reading this row and then mapping the remaining values with them. We will be using the following function that will act as a prototype function from array and string since it will help map the data ... Read More
In Java, maps are a powerful and versatile way to store key-value pairs. Often, you may find the need to merge the contents of one map into another. This can be done effortlessly using the putAll method available in the Map interface. Let's explore this functionality with an example and a step-by-step explanation. Problem Statement The goal is to combine two maps by adding all entries or selectively adding entries without overwriting existing ones in the destination map. Input Map 1 (Destination Map) Wallet: 700 Belt: 600 Map 2 (Source Map) Bag: 1100 Sunglasses: 2000 ... Read More
JavaScript is a versatile programming language widely used for web development. While it is known for its ability to enhance the interactivity of web pages, JavaScript also provides powerful algorithms for sorting, searching, and graph traversal. These algorithms are essential in solving complex problems efficiently. In this article, we will explore advanced JavaScript algorithms, including sorting algorithms like quicksort and mergesort, searching algorithms like binary search, and graph traversal algorithms like breadth-first search and depth-first search. Sorting Algorithms Sorting algorithms play a crucial role in organizing data in a specific order. JavaScript offers several efficient sorting algorithms, two of which ... Read More
