About Kotlin

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference.

About Haskell

Haskell is a purely functional programming language.

Palindrome Check Example: Kotlin vs Haskell

Palindrome Check in Kotlin

fun isPalindrome(str: String): Boolean {
    val clean = str.lowercase().filter { it.isLetterOrDigit() }
    return clean == clean.reversed()
}

fun main() {
    println(isPalindrome("A man, a plan, a canal: Panama")) // true
    println(isPalindrome("race a car")) // false
}

Palindrome Check in Haskell

import Data.Char (isAlphaNum, toLower)

isPalindrome :: String -> Bool
isPalindrome str = clean == reverse clean
  where clean = map toLower $ filter isAlphaNum str

main :: IO ()
main = do
  print $ isPalindrome "A man, a plan, a canal: Panama" -- True
  print $ isPalindrome "race a car" -- False

Bubble Sort Example: Kotlin vs Haskell

Bubble Sort in Kotlin

fun bubbleSort(arr: IntArray) {
    val n = arr.size
    for (i in 0 until n) {
        for (j in 0 until n - i - 1) {
            if (arr[j] > arr[j + 1]) {
                val temp = arr[j]
                arr[j] = arr[j + 1]
                arr[j + 1] = temp
            }
        }
    }
}

fun main() {
    val arr = intArrayOf(64, 34, 25, 12, 22, 11, 90)
    bubbleSort(arr)
    println(arr.joinToString(" "))
}

Bubble Sort in Haskell

bubbleSort :: Ord a => [a] -> [a]
bubbleSort xs = foldr (\_ -> bubble) xs [1..length xs - 1]
  where
    bubble [] = []
    bubble [x] = [x]
    bubble (x:y:xs)
      | x > y     = y : bubble (x:xs)
      | otherwise = x : bubble (y:xs)

main :: IO ()
main = print $ bubbleSort [64, 34, 25, 12, 22, 11, 90]
