In this problem, we need to find the total number of sub strings of length K containing at most X distinct vowels. We can solve the problem in two different ways. The first way is to get all sub strings and count distinct vowels in each sub string of length K. The second way is to use a map data structure and track the number of distinct vowels in the particular sub string. Problem statement– We have given string str of length N. The string contains only alphabetical characters. Also, we have given K and X positive integers. We need ... Read More
In Java, a matrix can be represented using a two-dimensional array. Matrices are used for storing and manipulating data that have a tabular structure. Matrices have several properties and operations associated with them, such as addition, subtraction, multiplication, transposition, and determinant calculation. As per the problem statement we have to Create a Matrix and Fill it with Palindrome Number. Let's start! For instance Suppose we have 4*5 matrix: After performing the operation on matrix, the result will be: Enter the number of rows: 4 Enter the number of columns: 5 Matrix with Palindrome ... Read More
In Java, a matrix can be represented using a two-dimensional array. Matrices are used for storing and manipulating data that have a tabular structure. Matrices have several properties and operations associated with them, such as addition, subtraction, multiplication, transposition, and determinant calculation. As per the problem statement we have to Create a Matrix and Fill it with Armstrong Number. Let's start! For instance Suppose we have 4*3 matrix: After performing the operation on matrix, the result will be: Enter the number of rows: 4 Enter the number of columns: 3 Armstrong Matrix: ... Read More
In Java, a matrix can be represented using a two-dimensional array. Matrices are used for storing and manipulating data that have a tabular structure. Matrices have several properties and operations associated with them, such as addition, subtraction, multiplication, transposition, and determinant calculation. As per the problem statement we have to add sum of all individual rows and columns. Then we need to perform the difference between these added rows and columns and display the result. Let's start! For instance Suppose the original matrix is: {4, 2, 1}, {3, 5, 6}, {8, 9, 7} After performing ... Read More
A polygon is a 2-dimensional closed shape that has at least 3 sides. Depending on the number of sides, relationships of the sides and angles, and other characteristics, polygons can be classified under different names like triangles, squares, and quadrilaterals. An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon. Exterior angle is defined as the angle formed between a side of triangle and an adjacent side extending outward. In this article, we will find interior and exterior angle of regular polygon when numbers of sides of polygon is ... Read More
In Java, the file separator is a character that separates the components of a file path. The file separator varies depending on the operating system on which the Java program is running. On Windows systems, the file separator is backslash (\). On Unix-based systems (such as Linux and macOS), the file separator is forward slash (/). Let's start! For instance Suppose that we running the code on windows system After performing the operation to get the separator, the result will be: Separator for this file system is: \ Algorithm Step-1: Import the necessary libraries. ...

In Java, the java.nio.file.FileStore class represents a storage pool, device, partition, volume, or other implementation-specific means of file storage. The FileStore class provides methods for querying information about the storage device, such as its total and available space, its file system type, and whether it supports certain features like file attributes or symbolic links. The type() method of the FileStore class returns a string representing the file store type. The file store type is a string that identifies the type of file system used by the file store. Examples of file system types include "NTFS" for the Windows NT ... Read More
In Java, you can use the File class to represent and manipulate file and directory paths. You can also use the File class to create, delete, and manipulate files and directories. To know where the actual file is getting stored in Java, you can use the getAbsolutePath() method of the File class. This method returns a string representation of the absolute path of the file, which includes the full path from the root directory to the file. Let's deep dive into the article to see where the actual file is getting saved in Java. For instance ... Read More
Introduction In machine learning, computer vision is a field where image datasets are used and analyzed to perform several complex tasks related to the same. Here different algorithms and techniques are used related to handling and analyzing the images in order to use the data and train high-performing models. Convolution is a very important term or a phenomenon that occurs in the name of Convolutional neural networks, which is the most famous technique used for handling and dealing with image datasets in machine learning. In this article, we will discuss convolution, what are convolutional operations, and other important ... Read More
Introduction In machine learning and data science, many statistical tests are used to compare and find the differences between variables or the features of the data. These tests are mainly hypothesis tests where the conditions are defined, and according to the different tests being conducted, the relationship between variables is assumed. The t-test is also a type of statistical test that is used to compare the means of different groups of the categorical variable. In this article, we will discuss the paired t-test, which is an extension or a type of t-test used in statistics, and we will ... Read More
