class Solution {
    fun firstPalindrome(words: Array<String>): String {
        for (word in words){
            if (isPalindrome(word)){
                println(word)
                return word
            }
        }

        return ""
    }
    fun isPalindrome(word:String):Boolean{
        var leftPointer = 0
        var rightPointer = word.length-1

        while (leftPointer<rightPointer){
            if (word[leftPointer]!=word[rightPointer]) {
                return false
            }
            leftPointer+=1
