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 Python, an element index refers to the position of an element within a sequence, such as a list or string. It represents the location of an element, starting from 0 for the first element and incrementing by 1 for each subsequent element. Assigning keys with the maximum element index means associating unique identifiers or labels with the highest possible index value in a sequence. This approach allows for easy access and retrieval of elements based on their positions using the assigned keys. Example Assume we have taken an input dictionary. We will now find the maximum element in the ... Read More

In Python, a set is an unordered collection of unique elements, represented by {}. It allows efficient membership testing and eliminates duplicate values, making it useful for tasks such as removing duplicates or checking for common elements between sets. Appending multiple elements to a set in Python is a common operation that involves adding multiple unique elements to an existing set. In this article, we will learn how to append multiple elements in a set in python. Example Assume we have taken an input set and input list. We will now append the input list elements to the input set ... 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 Python, a set is an unordered collection of unique elements, represented by {}. It allows efficient membership testing and eliminates duplicate values, making it useful for tasks such as removing duplicates or checking for common elements between sets. In this article, we will learn how to access the K element in a set without deletion in python. Example Assume we have taken an input set and K element. We will now find the index of that K element in an input set using the above methods. Input inputSet = {3, 9, 5, 1, 2, 8} k=5 Output The ... Read More

String consonants refer to the non-vowel sounds produced when pronouncing a string of characters or letters. In this article, we are going to study how to reverse only the consonants in a string without affecting the position of other elements using the following 2 methods in Python: Using append() and join() functions Using pop() function and string concatenation Example Before Reversing : tutorialspoint After Reversing: tunopiaslroitt Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task –. The function checkConsonant(char) is defined to check if a character is a consonant ... Read More

In this article we are going to learn how to check whether the input matrix is a Markov Matrix using nested for loops and sum() function. Before that let us understand what is Markov Matrix with an example? The matrix is said to be a Markov matrix if the sum of each row is equal to 1. Example [ [ 0, 1, 0 ], [ 0, 0.3, 0.7 ], [ 0, 0, 1 ]] In the above example, the sum of each row is 1. Hence the above matrix is an example of a Markov ... Read More

If a matrix produces the same matrix when multiplied by itself, it is said to be an idempotent matrix. If and only if M * M = M, the matrix M is considered to be an idempotent matrix. Where M is a square matrix in the idempotent matrix. Matrix M: 1 0 0 0 1 0 0 0 0 Performing M*M 1 0 0 * 1 0 0 = 1 0 0 0 1 0 0 1 0 ... Read More

A binary matrix is a rectangular grid in which each element is either 0 or 1, indicating true or false states. It is widely employed to represent relationships, connectivity, and patterns across various disciplines Assume we have taken a 2D binary input matrix containing N rows and M columns. T. We will now check whether the input matrix is horizontal or vertically symmetric or both using the below method. If the first row matches the last row, the second row matches the second last row, and so on, the matrix is said to be horizontally symmetric. If the first ... Read More

In this article, we will explore how to perform arithmetic operations between BigDecimal and Primitive data types by using Java. For instance, Addition: The sum of a BigDecimal object with a value of 10.50 and an int primitive with a value of 5 is a BigDecimal object with a value of 15.50. 10.50 + 5 = 15.50 SyntaxThe syntax doubleValue() method returns the value of a BigDecimal object as a double primitive type. double doubleNum1 = num1.doubleValue(); Where “num1” is a BigDecimal object. What is BigDecimal in Java? BigDecimal is a class in Java's java.math package that ... Read More
