Takahashi, who is A years old, is riding a Ferris wheel.

It costs B yen (B is an even number) to ride the Ferris wheel if you are 13 years old or older, but children between 6 and 12 years old (inclusive) can ride it for half the cost, and children who are 5 years old or younger are free of charge. (Yen is the currency of Japan.)

Find the cost of the Ferris wheel for Takahashi.

Constraints
