In this tutorial, we are going to learn how to develop a Haskell program to print 8 start patterns using the internal replicate and concat function. An '8' star pattern is an ASCII art representation of the number 8 using asterisks. as shown below − ******** * * * * ******** * * * * ******** The asterisks are arranged in such a way that they form the shape of the number 8. Algorithm Step 1 − ... Read More
In this tutorial, we are going to understand how to develop a Haskell program that will create a pyramid pattern of ‘&’ using mapM, forM, and recursive function. A pyramid ‘&’ pattern is a design or arrangement of ‘&’ or other symbols in the shape of a pyramid as shown below. & &&& &&&&& &&&&&&& &&&&&&&&& It is created by printing ‘&’ or symbols in multiple rows, starting from the top and moving downwards. Each row contains one more symbol than the previous row, creating the illusion of ... Read More
In Haskell we can use internal functions like mapM, forM or recursive functions to print square star pattern. A square star pattern is a two-dimensional pattern made up of stars (or asterisks, represented by the '*' symbol) arranged in the shape of a square as shown below. **** **** **** **** The square pattern is formed by printing a specified number of lines, each containing a specified number of stars. The pattern can be of any size, with the number of lines and the number of stars in each line determining the overall size of the square pattern. Algorithm ... Read More
In Haskell we can use mapM function and forM function to print a star Pascal’s Triangle. A star Pascal's triangle is a variation of the traditional Pascal's triangle that uses asterisks (or stars) instead of numbers to form a triangular pattern as shown below. * * * * * * * * * Pascal's triangle is a triangular array of numbers, where each number in the triangle is the sum of the two numbers above it. In ... Read More
In this article, we are going to learn how we can develop a haskell program to print mirror upper start triangle patterns using mapM function, and unliness functions. A mirror upper star triangle pattern is a pattern made up of stars (asterisks) that form a triangle shape, with the top of the triangle pointing upwards. The following star pattern will give you a better understanding of mirror upper start triangle pattern. * *** ***** ******* ********* The pattern is called "mirror" because the left and right sides of the ...

This tutorial will help us in printing the upper star triangle pattern using mapM function, forM function, and unliness functions in Haskell. An upper star triangle pattern is a graphical representation of a triangle made up of asterisks or stars as shown below. * ** *** **** ***** It's called an "upper" star triangle because the triangle starts at the top and the number of stars in each row decreases as we move down the triangle. Algorithm Step 1 − We will start with defining a user-defined function as printStars function. Step 2 − Program execution will be ... Read More
Authentication refers to the process of verifying the identity of an individual to make sure the user is exactly who they are claiming to be before giving access to a system. It is very important to authenticate a user to ensure the security as well as integrity of the system. Over the course of time, authentication has developed into much more advanced and secure methods. The methods of authentication now range from credentials like user id, password and OTP to finger print scan, face ID scan and much more. Authentication ensures that no sensitive resources are being shared with unauthorised ... Read More
Java is a high-level, object-oriented programming language that was first released in 1995. It was designed to be portable across platforms and devices, allowing developers to write code once and run it anywhere. Java is known for its simplicity, reliability, and security features, making it a popular choice for developing enterprise applications, mobile apps, games, and more. It has a large and active community of developers, resulting in a vast array of libraries and tools that make Java development even more efficient and effective. Java, the versatile programming language, celebrated its 25th anniversary in 2022. Despite its relative youth, ... Read More
Java is a high-level object-oriented programming language that offers a class-based development approach, enabling the creation of software solutions with minimal dependencies. It is a versatile language that provides several benefits, including simplicity, platform orientation, security, and cost-effectiveness in terms of hardware resources. Additionally, Java is known for its stability and reliability. However, there are some disadvantages of using Java, such as high memory consumption, unattractive graphical user interfaces, and complex coding requirements. Pros and Cons of Java Pros of Java Memory Safety − Java eliminates the risk of null pointer exceptions, dangling pointers, and memory leaks, which are ... Read More
Java and JavaScript are two programming languages that are often compared and pitted against each other, thanks to their similar names. However, they are fundamentally different languages, with their own unique strengths and applications. Java is a mature language that has been around for over two decades and is widely used for enterprise-level software development. It is known for its stability, security, and cross-platform compatibility. Java's static type checking system makes it a safer option for larger software projects. On the other hand, JavaScript is a dynamic language that is primarily used for front-end web development. It enables developers to ... Read More
