Palindrome Check Example: Lua vs Swift

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 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

Bubble Sort Example: Lua vs Swift

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 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)
