He can ask any questions whatsoever that can be answered with \"Yes\" or \"No\". All the rest agree beforehand to answer the questions like that: if the question’s last letter is a vowel, they answer \"Yes\" and if the last letter is a consonant, they answer \"No\". Of course, the sleuth knows nothing about it and his task is to understand that.\n\n            Unfortunately, Vasya is not very smart. After 5 hours of endless stupid questions everybody except Vasya got bored. That’s why Vasya’s friends ask you to write a program that would give answers instead of them.\n\n            The English alphabet vowels are: A, E, I, O, U, Y\n\n            The English alphabet consonants are: B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Z\n\n            Input\n            The single line contains a question represented by a non-empty line consisting of large and small Latin letters, spaces and a question mark.
