Complete the following code snippet, which is intended to be a recursive method that reverses a String value:
public static String reverseIt(String s)
{
if (s.length() <= 1)
{
return s;
}
else
{
________________________
}
}
A) return reverseIt(s.substring(0)) + s.charAt(1);
B) return reverseIt(s.substring(0)) + s.charAt(0);
C) return reverseIt(s.substring(1)) + s.charAt(1);
D) return reverseIt(s.substring(1)) + s.charAt(0);

The recursive call should pass in the substring of the original String, starting from the second character (index 1). This is done by calling s.substring(1). At each recursive step, the method adds the first character (s.charAt(0)) to the end of the reversed substring that was returned from the previous recursive call. This is achieved by using the + operator, so the complete statement is:
return reverseIt(s.substring(1)) + s.charAt(0);
