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
else if (s.charAt(low) != s.charAt(high)) // Base case
else
}
◦ 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 |
| | for (int i = 1; i <= high; i++) { |
| | // Swap the largest with the last number in the list |
| | list[indexOfMax] = list[high]; |
| | // Sort the remaining list |
}
}
◦ sort(list, list.length)
◦ sort(list)
◦ sort(list, list.length - 1)
◦ sort(list, list.length - 2)
