Palindrome Check Example: Kotlin vs Groovy

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 Groovy

def isPalindrome(String str) {
    def clean = str.toLowerCase().replaceAll(/[^a-z0-9]/, '')
    return clean == clean.reverse()
}

# Example usage
println isPalindrome("A man, a plan, a canal: Panama") // true
println isPalindrome("race a car") // false

Bubble Sort Example: Kotlin vs Groovy

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 Groovy

def bubbleSort(arr) {
    def n = arr.size()
    n.times { i ->
        (n - i - 1).times { j ->
            if (arr[j] > arr[j + 1]) {
                def temp = arr[j]
                arr[j] = arr[j + 1]
                arr[j + 1] = temp
            }
        }
    }
    return arr
}

def arr = [64, 34, 25, 12, 22, 11, 90]
println bubbleSort(arr.clone())
