Haskell Program to Check if two strings are anagram
In Haskell we can check if given two strings are anagram or not using sort function and freqMap. What is Anagram? An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the word "listen" is an anagram of the word "silent". Anagrams are often used in word play, puzzles, and other forms of entertainment. Algorithm Step 1 − The Data.List module is imported to use sort function. Step 2 − The isAnagram function using sort function is defined Step 3 ...
Read MoreHaskell Program to Check Palindrome
This tutorial will help us in checking if any number is palindrome number or not using user-defined function and boolean functions in haskell. A palindrome number is a number that remains the same when its digits are reversed. The following example will give you a clear idea about Palindrome number. For example, 121, 12321, and 1221 are palindrome numbers, while 123, 1234, and 1212 are not. Algorithm Step 1 − The isPalindrome function using reverse function is defined as, isPalindrome str = str == reverse str. Step 2 − Program execution will be started from main function. The ...
Read MoreHaskell Program to create Complex numbers from given imaginary parts
In this article we are going to use the internal function of Haskell like Data.complex and Prelude to create a complex number from a given imaginary parts. This tutorial will help us in creating the complex number from the given imaginary part. The imaginary part of a complex number is the coefficient of the imaginary unit, typically represented by the symbol "i", in the standard form of the complex number. A complex number can be represented in standard form as a + bi, where a is the real part and b is the imaginary part. Algorithm Step 1 − ...
Read MoreHaskell Program to convert double type variables to int
In Haskell, we will convert double type variables into int by using user-defined function, doubleToInt along with floor, round and ceiling functions. In the first example, we are going to use (doubleToInt d = floor d) function and in the second example, we are going to use (doubleToInt d = round d). And in the third example, we are going to use (doubleToInt d = ceiling d). Algorithm Step 1 − The doubleToInt function is defined using floor function as, doubleToInt d = floor d. Step 2 − The program execution will be started from main function. The ...
Read MoreHaskell Program to convert int type variables to String
In Haskell, we will convert int type variables into string by using user-defined function, intToString along with show, map and printf functions. In the first example, we are going to use (intToString n = show n) function and in the second example, we are going to use (intToString n = intercalate "" (map show [n])). And in the third example, we are going to use (intToString n = printf "%d" n). Algorithm Step 1 − The intToString function is defined using show function as, intToString n = show n. Step 2 − The program execution will be started ...
Read MoreHaskell Program to convert string type variables into int
In Haskell, we will convert string type variables into integer by using user-defined function, stringToInt along with read and readMaybe functions. This can also be implemented using pattern matching and recursion. In the first example, we are going to use (stringToInt str = readMaybe str) function and in the second example, we are going to use (stringToInt "" = Nothing; stringToInt ('-':xs) = negate ; stringToInt xs; stringToInt xs = case reads xs of [(n, "")] -> Just n and _ -> Nothing). Algorithm Step 1 − The stringToInt function is defined using readMaybe function Step 2 ...
Read MoreHaskell Program to convert string type variables into boolean
In Haskell, we will convert string type variables into boolean by using user-defined function, stringToBool along with Maybe Bool, toLower and readMaybe functions. In the first example, we are going to use (stringToBool :: String -> Maybe Bool) function and in the second example, we are going to use (stringToBool str = case map toLower str of). And in third example, we are going to use (stringToBool str = case readMaybe str of). Algorithm Step 1 − The stringToBool function is defined. Step 2 − The program execution will be started from main function. The main() function has whole ...
Read MoreHaskell Program to convert Hexadecimal to Decimal
This tutorial will help us to creat a haskell program that can covert a given hexadecimal number to a decimal number using revers, map and fold1 functions Hexadecimal to decimal conversion is the process of converting a number from the hexadecimal number system to the decimal number system. The hexadecimal number system uses a base of 16, which means that there are 16 unique symbols used to represent numbers in this system (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F). The decimal number system, on the other hand, uses a base of ...
Read MoreHaskell Program to convert Decimal to Octal
We can convert the Decimal number to an Octal using the recursion and unfoldr function of Haskell. Decimal to octal conversion is a process of converting a decimal (base-10) number to its equivalent representation in octal (base-8) numbering system. In decimal numbering system, we use 10 digits (0 to 9) to represent a number. In octal numbering system, we use 8 digits (0 to 7) to represent a number. To convert a decimal number to its equivalent octal representation, we divide the decimal number by 8 repeatedly until the quotient becomes 0, and keep track of the remainders. The remainders, ...
Read MoreHaskell Program to Print Hollow Right Triangle Star Pattern
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 ...
