Question 1

Fill in the code to complete the following method for checking whether a string is a palindrome.

public static boolean isPalindrome(String s) {
if (s.length() <= 1) // Base case
return true;
else if ________
return false;
else
return isPalindrome(s.substring(1, s.length() - 1));
}

◦ (s.charAt(0) != s.charAt(s.length())) // Base case
◦ (s.charAt(1) != s.charAt(s.length() - 1)) // Base case
◦ (s.charAt(0) != s.charAt(s.length() - 1)) // Base case
◦ (s.charAt(1) != s.charAt(s.length())) // Base case

Question 2

Analyze the following code:

public class Test {
public static void main(String[] args) {
int[] x = {1, 2, 3, 4, 5};
xMethod(x, 5);
}

public static void xMethod(int[] x, int length) {
System.out.print(" " + x[length - 1]);
xMethod(x, length - 1);
}
}
