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

Palindrome Check Example: Lua vs Kotlin

Palindrome Check in Lua

function isPalindrome(str)
    local clean = string.lower(string.gsub(str, "[^%w]", ""))
    return clean == string.reverse(clean)
end

-- 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: Lua vs Kotlin

Bubble Sort in Lua

function bubbleSort(arr)
    local n = #arr
    for i = 1, n do
        for j = 1, n - i do
            if arr[j] > arr[j + 1] then
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
            end
        end
    end
    return arr
end

local arr = {64, 34, 25, 12, 22, 11, 90}
local sorted = bubbleSort(arr)
print(table.concat(sorted, " "))

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(" "))
}
