How to Homogenize a Point in Java?
In this article we will see how to homogenize a point. Any point in the projective plane is represented by a triple (X, Y, Z), called homogeneous coordinates or projective coordinates of the point, where X, Y and Z are not all 0. The point represented by a given set of homogeneous coordinates is unchanged if the coordinates are multiplied by a common factor. As per the problem statement we have to homogenize a point by taking any common factor and multiplying it with the given points. Let’s start! To show you some instances Instance-1 Suppose the points are (10, ...
Read MoreHow to Find Single Digit Array Elements in Java?
In a given array with some random integer values, we have to find out the single digits available in the given array and print those single digit values as output. An array can contain positive or negative numbers irrespective of the number of digits in a number. As here all elements belong to numeric type. Note- Take a positive integer array. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given Array= [1, 12, 3, 4, 10, 15]. The single digit elements present in the ...
Read MoreFind Number of Sorted Rows in a Matrix in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is to count all the rows in a matrix that are sorted either in strictly increasing order or in strictly decreasing order. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix is{ { 5, 6, 7, 8 , ...
Read MoreFind Minimum Elements in Each Row of Matrix in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. As per the problem statement we have to find the minimum element present in every row of a given matrix of a multi-dimensional array. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix is = { {2, 3, 11, 4, 6}, ...
Read MoreCheck if a Matrix is Involutory or not in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. Involutory matrix is a square matrix which when multiplied by itself, gives back an identity matrix. Identity matrix is a matrix in which all elements are zero except the diagonals which are one. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose we have a matrix | 1 0 ...
Read MoreHow to Check if the Matrix is a Magic Square in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is to check if the matrix is a magic square or not. A matrix is said to be a magic square if the sum of elements of any row, column or diagonal is equal to a specific number. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose ...
Read MoreCheck if a Matrix is Markov Matrix or not in Java
Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. A square matrix is called a Markov matrix if all entries are nonnegative and the sum of each column vector is equal to 1. The Markov matrix represents steps in a Markov chain. Each input of the Markov matrix represents the probability of an outcome. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some ...
Read MoreCheck if a Matrix is Identity Matrix or not in Java?
Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. Identity matrix is a square matrix which has all 1s as its principal diagonal elements and rest are 0s. As per the problem statement we have to0 check if the given matrix is Identity matrix or not. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose we have a matrix ...
Read MoreFind Two Array Elements Having Maximum Sum in Java?
Two elements giving the maximum sum in an array means, we have to find two largest array elements which will eventually give the maximum sum possible. In this article we will see how we can find the maximum sum of two elements in Java. To show you some instances Instance-1 Suppose we have the below array [10, 2, 3, -5, 99, 12, 0, -1] In this array the largest element is 99 and second largest is 12. Max sum = 99 + 12 Hence the maximum sum of two elements in this array is 111. Instance-2 Suppose we have the ...
Read MoreFind Two Array Elements Having Maximum Product in Java?
Two elements giving the maximum product in an array means, we have to find two largest array elements which will eventually give the maximum product possible. In this article we will see how we can find the maximum product of two elements in Java. To show you some instances Instance-1 Suppose we have the below array [10, 2, 3, -5, 99, 12, 0, -1] In this array the largest element is 99 and second largest is 12. Max product = 99 * 12 Hence the maximum product of two elements in this array is 1188. Instance-2 Suppose we have the ...
