# Pay the Bill

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**.

#### Input

) - the bill received at the restaurant.^{18}
