After eating at the restaurant, Barysh asked for the bill. It turned out that Barysh's order cost n manats. Baris always give tips 10% of the bill when paying, but if the total amount is less than the full manat, Barysh adds the amount to the full manat, because he does not have a penny and does not want to pay by card.

For example, if the bill is 17 manats, then Barish thinks to give another 1.7 manats. The total amount is 18.7 manats. In this case, Baris pays AZN 19.
