我如何编码它遍历列表并生成TRUE FALSE TRUE

randomphrase = ['lanal', 'samuel is my cat', 'too hot to hoot']
print(is_palindrome(randomphrase))

Answer 1

import java.util.ArrayList;
import java.util.Arrays;

public class StackOverflow {    

    public static void main(String args[]) {

        ArrayList<String> randomPhrases = new ArrayList<>(Arrays.asList("lanal", "samuel is a cat", "too hot to hoot"));

        // I loop through the list and check if each string is a palindrome
        for (String str : randomPhrases) {
            isPalindrome(str);
        }
    }

    private static boolean isPalindrome(String str) {

        //test for end of recursion
        if (str.length() < 2) {
            System.out.println("true");
            return true;
        }

        //check first and last character for equality
        if (str.charAt(0) != str.charAt(str.length() - 1)) {
            System.out.println("false");
            return false;
        }

        //recursion call
        return isPalindrome(str.substring(1, str.length() - 1));

    }
}
