The words "learned" and "learnt" are both past tenses of the verb "learn, " and but they have the same meaning, how they are used differs by location. In British English and other parts of the world, "learnt" is more common, but "learned" is the preferred form in the US and Canada. The worldwide nature of English can be seen in both variants, which are widely recognized despite the difference.Is it "learned" or "learnt"?The past tense and past participle forms of the verb "learn" are "learned" and "learnt". They can be used equally in both situations, however their usage varies ... Read More
Sometimes while working with objects in JavaScript we want to filter objects based on keys. We can easily do this by using Lodash, a popular JavaScript library that provides several inbuilt functions to achieve this easily. In this article, we are going to discuss how we can Filter Objects by Keys using Lodash. Prerequisite Lodash: Lodash is a popular JavaScript library used to deal with a variety of functions such as arrays, objects, strings, and more. Install Lodash We can install the Lodash library in the project by adding it via CDN or ... Read More
Sometimes, we need to find the beginning and end of the day using MomentJS. This functionality has different real-life applications, such as filtering data within a day’s range, generating daily reports, and scheduling tasks at specific times. In this article, we will discuss how to find the beginning and end of the day using MomentJS. Prerequisite Moment.js: Moment.js is a popular JavaScript library used to deal with dates. This library is used to modify, parse, validate, manipulate, and display dates and times in JavaScript. Install Moment.js We can install the Moment.js library in ... Read More
In this article, we will learn to find three numbers in an array that add up to a given sum value using JavaScript. We are going to write a JavaScript program to find a triplet that sums up a given value. This program will make use of nested loops to iterate over the input array and check for the existence of a triplet with a sum equal to the given value. We'll present two different approaches and analyze their implementations. Sorting and Two-Pointer Technique The first approach uses sorting and the two-pointer technique to solve the problem efficiently. This method ... Read More
In this tutorial, we will discuss two approaches to finding the intersection point of two linked lists in JavaScript. The first approach involves using the loops, and the second approach involves using the difference of nodes technique which works in the linear time. We will be given two linked lists that are not sorted. Note that there is another version of this problem in which we are given a sorted pair of linked lists and have to find the intersection. We have to find the elements after which all the elements in both linked lists are the same. We will ... Read More
In this article, we are going to explore a Javascript program that works with a sorted array containing duplicate elements. The task is to traverse the array using a loop and identify both the index of the last duplicate element and the duplicate number. Introduction to Problem In the given problem we have to find the last duplicate element in a sorted array. Duplicate means the number is present more than one time. Example − Input arr[] = {1, 2, 2, 3, 5, 5, 6, 7} Output Last index: 5 Last duplicate value: 5 From the above given sorted array, ... Read More
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
