2) A palindrome is a string that reads the same both forward and backward. Some examples are "ABBA" "123343321" "otto" Write a function that takes a string as an argument and returns the int value 1 if the string is a palindrome and returns 0 otherwise. Write another function to check whether a string is palindrome or not and modify it so that uppercase alphabets are ignored in the matching process. Under this rule, the following strings (if taken as input) are examples of palindromes: "Otto", AbBa. (20 points)
