Haskell Program to get the Division and Remainder using library function
In Haskell, we can use divMod and quotRem functions to get the division and remainder of a given number. In the first example, we are going to use (divMod x y) function and in the second example, we are going to use (quotRem 20 7) function. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 2 − The variables named, “x” and “y” are being initialized. The interal function will divide them by taking them as argument. Step ...
Read MoreHaskell Program to get the real part from a Complex number
In Haskell, we can use realPart function and pattern matching to get the real part from a complex number. In the first example we are going to use (realPart c) function and in the second example, we are going to use patter matching as (x:+_) = c. Algorithm Step 1 − The Data.Complex module is imported to work over the complex numbers. Step 2 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 3 − The variable named, “c” is being ...
Read MoreHaskell Program to check a given number is finite or not
In Haskell, we can use isIEEE, isInfinite and isNaN functions to check whether a given number is finite or not. In the first example we are going to use (isIEEE n) function with if-else statement and in the second example, we are going to use (isInfinite n) function. And in third example, we are going to use (isNaN) function along with (isInfinite n) function. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 2 − The variable named, ...
Read MoreHaskell Program to get the numerator from a rational number
In Haskell, we can use numerator, div, quot and gcd functions to find the numerator from a given rational number. In the first example we are going to use numerator (r) function and in the second example, we are going to use (n `div` gcd n d) function. And in third example, we are going to use (numerator r `quot` gcd (numerator r) (denominator r)) function. Algorithm Step 1 − The Data.Ratio module is imported to use numerator function. Step 2 − Program execution will be started from main function. The main() function has whole control of the program. ...
Read MoreHow to send button value to PHP backend via POST using ajax?
AJAX (Asynchronous JavaScript and XML) makes web pages more responsive, interactive, and dynamic by enabling server communication without requiring a page to load. JavaScript is used to send and receive data from a server using various technologies, including XML, JSON, and HTML. In these, JSON is the most popular. AJAX is frequently used to transmit information from a web page to a server-side script, like a PHP script. The XMLHttpRequest object, included in most contemporary web browsers, can be used for this. You can establish a connection to a given URL, send data to that URL, and then wait ...
Read MoreHow to Check Orientation of 3 Ordered Points in Java?
In this article we are going to find the orientation of 3 ordered points. Here orientation means that the given points form clockwise, anticlockwise or collinear shape in space. In the above diagram a, b, c are the three points which check the orientation of shape in space. We find the orientation of three given points by calculating the slope. To calculate slope and to calculate the orientation of 3 ordered points. Slope of line segmentSlope of line segment $(a, b):\theta=\left ( y_{b}-y_{a} \right )/\left ( x_{b} -x_{a}\right )$ Slope of line segment $(b, c):\phi=\left ( y_{c} -y_{b}\right )/(x_{c}-x_{b})$ And ...
Read MorePandas series Vs. single-column DataFrame
Introduction This article compares and contrasts Python's Pandas library's single-column DataFrames and Pandas Series data structures. The goal of the paper is to clearly explain the two data structures, their similarities and differences. To assist readers in selecting the best alternative for their particular use case, it contains comparisons between the two structures and practical examples on aspects like data type, indexing, slicing, and performance. The essay is appropriate for Python programmers at the basic and intermediate levels who are already familiar with Pandas and wish to get a deeper grasp of these two key data structures. What is Pandas? ...
Read MoreJava Program to Encode a Message Using Playfair Cipher
Encrypting is the task of transforming information into an unreadable format or cipher text. It is usually done to protect the confidentiality of information. There are many ways and algorithms to encrypt data. One such example is the Playfair cipher algorithm. In this article, we are going to see how to write a Java program to encode a message using Playfair cipher. Playfair cipher makes use of a 5X5 grid or matrix and a set of pre-defined rules. To encrypt, we require a key and the plain text to be encrypted. Steps Now let us see the steps to encrypt ...
Read MoreReplace the Matrix Elements by Its Square 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. As per the problem statement the task is replace the matrix elements by its square. 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 {{8, 3, 2}, {12, 7, 9}, {6, 4, 10}}; After replacing the matrix element by its square, the result matrix will be 64 ...
Read MoreHow to Get File Owner's Name in Java?
As per the problem statement, we are going to find the file owner name in Java. The owner’s name here represents the owner of the PC in which file is being runned. To find the file owner in Java we will use the getOwner() method of the FileOwnerAttributeView class. FileOwnerAttributeView belongs to the java.nio class. 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 given file location is “D:/saket.txt”. After checking for Owner name of the given file, the output will be − ...
