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) {
return isPalindrome(s, 0, s.length() - 1);
}

public static boolean isPalindrome(String s, int low, int high) {
if (high <= low) // Base case
return true;
else if (s.charAt(low) != s.charAt(high)) // Base case
return false;
else
return ________;
}

◦ isPalindrome(s)
◦ isPalindrome(s, low + 1, high)
◦ isPalindrome(s, low + 1, high - 1)
◦ isPalindrome(s, low, high - 1)
◦ isPalindrome(s, low, high)

Question 2

Fill in the code to complete the following method for sorting a list.

public static void sort(double[] list) {
________;
}

public static void sort(double[] list, int high) {
if (high > 1) {
// Find the largest number and its index
int indexOfMax = 0;
double max = list[0];
for (int i = 1; i <= high; i++) {
if (list[i] > max) {
max = list[i];
indexOfMax = i;
}
}
// Swap the largest with the last number in the list
list[indexOfMax] = list[high];
list[high] = max;
// Sort the remaining list
sort(list, high - 1);
}
}

◦ sort(list, list.length)
◦ sort(list)
◦ sort(list, list.length - 1)
◦ sort(list, list.length - 2)
