A palindrome is a word or phrase whose letters read the same forwards and backwards.

The letters are the 26 letters of the latin Alphabet (a-zA-Z), ignoring spaces, punctuation, and case.

Write code which returns a 1 if its character array argument is a palindrome, 0 otherwise.

For simplicity"s sake, you may assume that the array is all one case.
