Palindrome Check Example: Swift vs Kotlin

Palindrome Check in Swift

func isPalindrome(_ str: String) -> Bool {
    let clean = str.lowercased().filter { $0.isLetter || $0.isNumber }
    return clean == String(clean.reversed())
}

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

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
}

Bubble Sort Example: Swift vs Kotlin

Bubble Sort in Swift

func bubbleSort(_ arr: inout [Int]) {
    let n = arr.count
    for i in 0..<n {
        for j in 0..<(n - i - 1) {
            if arr[j] > arr[j + 1] {
                arr.swapAt(j, j + 1)
            }
        }
    }
}

# Example usage
var arr = [64, 34, 25, 12, 22, 11, 90]
bubbleSort(&arr)
print(arr)

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(" "))
}
