# Question: Arpasland has surrounded by attackers. A truck enters the city. The driver claims the load
#           is food and medicine from Iranians.Arun is one of the soldiers in Arpasland. He doubts about
#           the truck, maybe it's from the siege. He knows that a tag is valid if the sum of every two
#           consecutive digits of it is even and its letter is not a vowel.
#           Determine if the tag of the truck is valid or invalid.
# Consider the letters A, E, I, O, U, Y  to be vowels for this problem.
