Problem Statement For an index and an arr[]. Check if the array[] can be partitioned into two disjoint sets, excluding arr[index] such that the sum of both sets has equal value. Example 1 Input arr[] = {4, 3, 1, 2}, Index = 1 Output No Explanation We have to exclude arr[1] = 3 All possible sets are − Set 1: (4), Set 2: (2, 1), sum = 4≠3 Set 1: (4, 1), Set 2: (2), sum = 5≠2 Set 1: (4, 2), Set 2: (1), sum = 6≠1 No combination satisfies the conditions. Example 2Input arr[] ... Read More

A square triangular number, also referred to as a triangular square number, is a number that is both a triangular number and a perfect square. Square triangular numbers have an unlimited number of possible values; the first few are − 0, 1, 36, 1225, 41616... A triangular number or triangle number counts objects arranged in an equilateral triangle. The nth triangular number is the number of dots in the triangular arrangement with n dots on each side and is equal to the sum of the n natural numbers from 1 to n. The sequence of triangular numbers, ... Read More

Introduction Missing data is a common issue in data analysis and can occur due to various reasons. In Python, missing values are often represented as NaN (Not a Number) or None. Missing data can cause inaccurate analysis results and lead to biased conclusions if not handled properly. Therefore, handling missing data is an essential part of any successful data analysis project. Causes of Missing Data in Python Missing data is a common challenge that data analysts and scientists often encounter in their work. In Python, there are various reasons why data may be missing. Understanding these causes can help analysts ... Read More

Introduction Pygame is the module used for game development in Python; it is considered to be one of the most effective modules for this purpose. The development of video games can not only be profitable in today's market but also serve as a medium for educational and promotional purposes. Creating games requires knowledge of mathematics, logic, physics, artificial intelligence, and a lot of other subjects, yet it can be really enjoyable. We will discuss in detail what is Pygame, how to implement a normal PyGame window and how to allow users to resize the window with a working example. ... Read More

Introduction A data structure known as a data frame is a two-dimensional labelled array with columns that might be of various data kinds. You can compare it to a spreadsheet, a SQL table, or even a dict of Series objects to better understand it. It is the panda item that is used the vast majority of the time. In addition to the data itself, you have the option of also passing parameters for the index (row labels) and columns (column labels). If you supply an index and/or columns, you are assuring that those elements will be present in the DataFrame ... Read More

Introduction A heat map, is a graphical representation of data in which each value in a matrix is assigned a unique colour. The primary purpose of heat maps is to increase the accuracy of the visualization of the total number of places and events included within a dataset, as well as the accuracy with which they direct viewers' attention to the most important aspects of data visualizations. Heat maps, which rely on colour to communicate values, are most commonly used to offer a more holistic picture of numerical values. This is due to the fact that heat maps rely on ... Read More

Introduction Animated pictures are a sequence of static images that are automatically played to display relevant material in a continuous and dynamic manner, and they have the benefit of being smaller than videos. Additionally, many online and mobile applications enable animated images in the same manner that they support static photos, although they do not always permit the upload of movies. In this situation, animated pictures can be really helpful. Clearly, there are several other reasons why animated graphics are preferable. Sometimes, combining similar or unrelated photos is simply for fun. In this article, we would learn the steps to ... Read More

Introduction Machine learning's influence in IT and other industries is expanding rapidly. Despite still being in its early stages, Machine Learning has gained a lot of attention across industries. It's the study of how to program computers to learn and improve on their own. Therefore, Machine Learning is concerned with improving computer programs by utilizing data gathered from a wide range of observations. In this article, titled "Aspects of Machine Learning process, " we will explore some of the foundational ideas behind Machine Learning, including its definition, the technologies and algorithms it employs, its potential applications and examples, and more. ...

Introduction The ratio of accurate predictions to inaccurate predictions is plotted in a matrix known as a confusion matrix. This would refer to the ratio of true negatives and true positives (right predictions) to false negatives and false positives for a binary classifier (incorrect predictions). After data cleaning, preprocessing, and parsing, the first thing we do is feed the data to an efficient model, which naturally produces results in probabilities. Hold on though! But how do we assess the performance of our model? Higher performance, better effectiveness—exactly that's what we want. And here’s when the Confusion matrix comes into ... Read More

Introduction These days, Java and C++ are widely utilized in competitive programming. These two programming languages are utilized generally in industry and competitive programming due to their impressive characteristics. C++ is a commonly used programming language due to its efficiency, fast speed, and dynamic memory use. In terms of software development, Java is incomparable to any other programming language. Java is extensively utilized in the IT sector. Now we will look into how Java and C++ are similar. What is Java? Java is an Object-Oriented programming, general-purpose, and high-level language. It is mainly used for coding web applications. Java ... Read More
