Problem:
Score : 100 points

Problem Statement

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

0 ≤ A ≤ 100

2 ≤ B ≤ 1000

B is an even number.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the cost of the Ferris wheel for Takahashi.

Sample Input 1

30 100

Sample Output 1

100

Takahashi is 30 years old now, and the cost of the Ferris wheel is 100 yen.

Sample Input 2

12 100

Sample Output 2

50

Takahashi is 12 years old, and the cost of the Ferris wheel is the half of 100 yen, that is, 50 yen.

Sample Input 3

0 100

Sample Output 3

0

Takahashi is 0 years old, and he can ride the Ferris wheel for free.
