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.

Solution in C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <iostream>

using namespace std;

int main()
{
  int A,B;
  cin>>A>>B;
  if(B>=2 && B<=1000 && B%2==0){
  if(A>=13 && A<=100 ){
        cout<<B<<endl;
    cout<<"Takahashi is "<<A<<" years old now, and the cost of the Ferris wheel is "<<B<<" yen."<<endl;
  }
  else if(A<=12 && A>=6){
      cout<<B/2<<endl;
    cout<<"Takahashi is "<<A<<" years old, and the cost of the Ferris wheel is the half of "<<B<<" yen, that is, "<<B/2<<" yen"<<endl;
  }
  else if (A>=0 && A<6){
      cout<<0<<endl;

    cout<<"Takahashi is" <<A<<" years old, and he can ride the Ferris wheel for free"<<endl;

  }}

    return 0;
