Check if each letter \(i\) in the range \(0, S/2\), where \(S\) is the size of the word, is equal to its corresponding letter (\(S-i-1\)). If it isn't, then break the loop early and print NAY otherwise print YAY after searching the whole word.

Time Complexity: \(\mathcal{O}(S)\), where \(S\) is the length of the word.
