In this tutorial, we discuss writing a program to sort elements in lexicographical order in the Haskell programming language. Haskell is a Declarative, Strongly Typed, and Functional programming language. The computations in Haskell are mathematical functions. The lexicographical order is a dictionary order or in the order of the ASCII values of a character. In this tutorial, we see two different ways to implement a program to sort elements in lexicographical order in Haskell. Program to sort elements in lexicographical order using built-in function sort. Program to sort elements in lexicographical order using custom sorting functions. Algorithm steps ... Read More
In this tutorial, we discuss writing a program to print ASCII values in the Haskell programming language. Haskell is a Declarative, Strongly Typed, and Functional programming language. The computations in Haskell are mathematical functions. ASCII stands for American Standard Code for Information Interchange, used in electronic data transfer and communication. These ASCII values represent characters in electronic devices. These values are used to describe characters and data in digital devices. ASCII is a 7-bit number representing a character. Example: 7-bit binary “1100001” represents character ‘a’ whose ASCII value is 97. In this tutorial, we see two different ways to print ... Read More
In this tutorial, we discuss writing a program to find the largest among the three numbers Haskell programming language We are going to learn three different ways to implement programs to find the largest among three numbers in Haskell. Program to find the largest among three numbers using if-else. Program to find the largest among three numbers using function max. Program to find the largest among three numbers using function maximum. Syntax variables in functions returning IO actions can be declared and initialized instantaneously using the “let” keyword. let num=100 The above line loads an Integer value ... Read More
In this tutorial, we discuss writing a program to find the largest among the three numbers Haskell programming language. A quadratic equation is a second-degree algebraic equation. Example − a quadratic equation is of the form ax^2 + bx + c, where a, b, and c are constants and x is variable. A quadratic equation has two roots. Algorithm steps Take a quadratic equation as input. Implement the programming logic to compute the roots. Display the roots. Algorithm Logic Take input or initialize values for a, b, and c. As the quadratic expression can be constructed with ...

In this tutorial, we discuss writing a program to count the number of vowels and consonants in a Sentence in the Haskell programming language. Haskell is a Declarative, Strongly Typed, and Functional programming language. The computations in Haskell are mathematical functions. Vowels are the open sound-producing letters in English literature. The list of vowels in the English alphabet is ‘a’, ’e’, ’i’, ’o’, and ’u’. The other letters are consonants. In this tutorial, we see two different ways to implement the program to count the number of vowels and consonants in Haskell. Implementing the program to count the number ... Read More
In this tutorial, we discuss writing a program to compute the quotient and remainder in Haskell programming language. Quotient and remainder are the quantities obtained as a result of dividing two quantities. Example − quotient and remainder for the division of 31/5 are 6, 1 respectively. The number can be represented as 31 (dividend) = 5(divisor) * 6(quotient) + 1(remainder). In this tutorial, we see four different ways to write a program to compute quotient and remainder. Haskell program to compute the quotient and the remainder using built-in functions div and mod Haskell program to compute the quotient and ... Read More
In this tutorial, we discuss writing a program to check if two of three Boolean variables are true in the Haskell programming language Boolean variables are the type of variable which hold the boolean value true and false. In this tutorial, we see two different ways to implement a program to check if two of the three boolean values are true Program to check if two of the three boolean values are true in an iterative method. Program to check if two of the three boolean values are true in a recursive method. Algorithm steps Declare or ... Read More
In this tutorial, we discuss writing a program to calculate the sum of the natural numbers in the Haskell programming language. Natural numbers are positive integers starting from 1, 2, 3...N In this tutorial, we see different ways to implement a program to compute the sum of natural numbers. Program to compute the sum of the natural numbers using a mathematical formula. Program to compute the sum of the natural numbers using a recursive function. Program to compute the sum of the natural numbers using the list method/function sum. Algorithm steps Declare or take input the range ... Read More
In this tutorial, we discuss writing a program to calculate simple and compound interest in the Haskell programming language In this tutorial, we see Program to compute Simple interest. Program to compute Compound interest. Simple interest is an Interest method for an investment, where interest is defined as I = p*t*r/100, where p is the invested amount, t is the quantity of time in years, and r is the interest rate. (per 100). Example − For an invested amount of 1000(p), t= 2 and r =3 the interest is 60. Compound interest is an Interest method for an ... Read More
In this tutorial, let us discuss how to validate URL addresses in JavaScript. A URL or Uniform Resource Locator identifies web pages, images, and videos on the internet. URLs are website addresses that transfer files, send emails, and many more. URLs consist of a protocol, domain name, and so on. URL indicates how the browser gets the data and where to get the data. We use a URL in the anchor tags or buttons to navigate the user to another location. We must verify the URL's validity before using it. URL Rule URL must start with http:// or https://. ... Read More
