Question: Recursion. Rewrite your solution to Exercise which prints a string backwards to use recursion. Use recursion to print a string forward and backward.
Exercise: Strings.
(a) Display a string one character-at-a-time forward and backward as well.
(b) Determine if two strings match (without using comparison operators or the cmp() built-in function) by scanning each string. EXTRA CREDIT: Add case insensitivity to your solution.
(c) Determine if a string is palindromic (the same backwards as it is for wards). EXTRA CREDIT: add code to suppress symbols and white space if you want to process anything other than strict palindromes.
(d) Take a string and append a backwards copy of that string, making a palindrome.
