fun isPalindrome(str: String): Boolean {
    // Normalize the string: remove spaces and convert to lowercase
    val normalizedStr = str.replace(Regex("\\s+"), "").lowercase()

    // Reverse the normalized string and compare
    val reversedStr = normalizedStr.reversed()

    return normalizedStr == reversedStr
}

fun main() {
    println("Is palindrome: ${isPalindrome("A man a plan a canal Panama")}")
    println("Is palindrome: ${isPalindrome("abcDefg")}")
}


 
/*
run:
 
Is palindrome: true
Is palindrome: false
 
*/
