In Haskell we can use the replicate function and recursive function to create a hollow right triangle star pattern. A hollow right triangle star pattern is a pattern made up of asterisks (*) that forms a right triangle shape with empty spaces in the middle as shown below. ** * * * * * * * * * * * * ******** The shape is created by printing asterisks in a specific order, with the number of asterisks in each row increasing as the ...

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

Regex or Regular Expression is the language used for pattern-matching and string manipulation. It consists of a sequence of characters that define a search pattern and can be used for performing actions like search, replace, and even validate on text input. A regular expression consists of a series of characters and symbols that amount to form a search pattern. In this article, we are going to see how to write a Java program to extract a single quote-enclosed string from a larger string using Regex. Java provides support for regex from the java.util.regex package. The pattern class represents a compiled ... Read More

There are 5 weekdays in a week, which are Monday, Tuesday, Wednesday, Thursday and Friday. The two remaining days i.e. Saturday and Sunday make up the weekend. In this article, we will learn how to write a Java program to display name of the weekdays in a calendar year. Using the DateFormatSymbols Class The Java standard library's java.text package contains the DateFormatSymbols class which provides methods for retrieving and setting the following date and time symbols − Month and day names and abbreviations Day of the week names and abbreviations Era names AM/PM strings Time Zone Names and ...

A year has 12 months which are named January, February, March, April, May, June, July, August, September, October, November, December. These are the complete names of the months and there are multiple ways to represent them like short format, complete format, MM or 2 integers format. In this article, we are going to see how to display names of months of calendar year in short format with the help of Java. There are numerous ways to do so and are as follows − Using a String Array ... Read More
