Find Scalar Multiplication of a 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. Scalar multiplication is nothing but multiplication between a matrix and a real number. The result of this multiplication is in matrix format. As per the problem statement, we have to find the scalar multiplication of a matrix. 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 ...
Read MoreFind index of 0 or Any Negative Integer Element Present in Array in Java
As per the problem statement, we have given an array with some random integer values and we have to find out and print the index which contains any zero or negative values. Note - Take an 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, 2, -3, -4, 0, 5] The index contains Zero and negative values = 2, 3, 4 Instance-2 Given Array= [-1, 0, 4, 6, 8, -5] The index contains Zero and negative values = 0, 1, ...
Read MoreHaskell Program to calculate the value from the given fraction and exponent
This haskell tutorial will help us in calculating the value from the given fraction and exponent of a number. To find this, the input is taken as fraction and exponent, and its corresponding value is computed. Algorithm Step 1 − The “Data.Ratio” is imported to work over fractions. Step 2 − The calculateValue function is defined Step 3 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 4 − The variables named, “fraction” and “exponent” are initialized. ...
Read MoreFind Array Elements Which are Greater than its Left Elements in Java?
An array is a linear data structure in which elements are stored in contiguous memory locations. As per the problem statement, we have given an array with some random integer values and we have to find out the numbers which are greater than its all left elements by using Java programming language. Let’s start! To show you some instances Instance-1 Given Array= [1, 2, -3, -4, 0, 5]. The numbers which are greater than its all left elements = 2, 5 Instance-2 Given Array= [-1, 0, 4, 6, 8, -5]. The numbers which are greater than its all left ...
Read MoreGolang program to include a module inside the class
In Go programming language, a new module is initiated using init command after which we can import other modules in our code. There is no concept of class in Go, only structs are used. In this article, we will use one example to include a module inside the class. In this example, we will create a Circle struct whose area will be printed on the console. For this example, we will import math and fmt packages outside the struct but they can be used anywhere. The print statement is executed using Printf function from the fmt package. Algorithm Import ...
Read MoreGolang program to create a block using curly braces
We can create a block in golang using curly braces and then create a variable inside the block to have the scope only inside the block and not outside it. In this article, we will use three examples to create a block using curly braces. In the first example few statements will be printed inside and outside the block, in the second example comparison value will be printed inside the block and in the third example function will be used to demonstrate the use of block. Algorithm Import the required packages in the program Create a main function In ...
Read MoreGolang program to convert the hash collection into string
Golang has json package that is used for converting the hask collection into strin. A hashmap belongs to hash collection which stores the data as key:value pairs, whereas a string is a sequence of characters and it is immutable. In this article, we will use two examples to convert the hash collection into string. In the first example, the Json package will be used to convert the map to encoded byte array whereas in the second example sort package will be use along the loops. Syntax json.Marshal() This function belongs to the JSON package and it converts the value ...
Read MoreGolang program to demonstrate the time arithmetic
We are going to calculate the current time using the Now function from time package in Go programming language for demonstrating the time arithmetic. The time arithmetic is calculated using mathematical functions. In both examples, we will use mathematical calculations to find the past, future and the duration using Sub function. The output is printed using Println function from the fmt package. Syntax func Now() Time The Now() function is defined in time package. This function generates the current local time. To use this function, we have to first import the time package in our program. func sub() ...
Read MoreFind Array Elements Which are Greater Than Its Immediate Left Element?
As per the problem statement, we have an array with some random integer values and we need to find out the numbers which are greater than its immediate left element. Note - Take an 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, 2, -3, -4, 0, 5]. The numbers which are greater than its left element = 2, 0, 5 Instance-2 Given Array= [-1, 0, 4, 6, 8, -5]. The numbers which are greater than its left element = ...
Read MoreFind All Possible Coordinates of a Parallelogram in Java?
A parallelogram refers to the quadrilateral which has two pairs of parallel sides where opposite sides are equal in length, and the opposite angles are equal in measure. In this article we are going to find all possible coordinates of a Parallelogram. Basically, we will find all the possible coordinates from the given three coordinates to make a parallelogram of a non-zero area. Here the three given coordinates are not fixed points and can change. Therefore, if three coordinates are given, we may claim that there are only three coordinates from which we can build a parallelogram. As per ...
