ignore case, iternational, etc
strip white space, symbols, numerals etc
get length of string
divide by two = base length
if not divisible by two -"not palindrome"
net length = base length - 2 // you do not have to compare the last two letters if all others match.
compare first and last character
if no match - "not palindrome"
compare second and second last........
this is bloody rough, hope you get the gist
