Just another way to check if a word is palindromic or not.
In my country (Greece) if a word is palindromic we say it is
"καρκινική" that's why i named the fuction in the code kark().
-What it does?
If we would say that word has n letters,then this
compares the first with the n letter, next the second with the n-1 letter and so on..
e.g. let's take the name "anna"
compares the first 'a' with the last 'a'
and the two 'n' in between.
a n n a |--| |-----|
Hope it's helpful...:)
