Consider the following recursive function for checking if a string is a palindrome. A palindrome is a word spelled the same both forward and backwards i.e. "tacocat". public boolean isPalindrome (String str) { if(str.length() < 2) return true; else return str.charAt(0) str.charAt(str.length()-1) && isPalindrome (str.substring(0, str.length())); } This will not work! What is the issue and how can it be fixed?
