2. Consider the following recursive algorithm implemented as a Java method:
public static boolean isPalindrome (String s) {
if (s.length()
return true;
==
0) {
}
else if (s.length()
return true;
}
==
1) {{
}
else if (s.charAt(0) !=s.charAt(s. .length()-1)) {
return false;
}
else {
return isPalindrome (s.substring(1, s.length()-2));
a.Briefly describe an input that will cause the worst-case performance for this
algorithm.
b.Assuming that the recursive call takes 15 basic operations, a return statement
takes 3 basic operations and that any of the if statements takes 7 basic
operations, give a recurrence describing the worst-case running time for this
algorithm.
