[Solved] Newton has shifted to a new house and it came to his notice

Socket: Newton has shifted to a new house and it came to his notice that there is only one socket in his house !!!

Newton does a lot of experiments using electricity and wants at least B sockets in his house.

Furthermore, he has ample amount of extension cords and each extension has A sockets and takes one socket. In others words, an extension cord extends one socket into A sockets.

You need to tell Newton how many extension cords will be required so that he can have at least B sockets.

Input

The first and the only line of the input contains 2 single integers A and B

Constraints:
1) 2 ≤ A ≤ 200
2) 1 ≤ B ≤ 200

Output

Print the answer

Example

Sample Input 1:
4 10

Sample Output 1:
3

Sample Explanation 1:
3 power strips, each with 4 sockets, extend the socket into 10 empty sockets.

Sample Input 2:
8 9

Sample Output 2:
2

Solution

class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
        int count = 0;
        int sum = 1;
        while (sum < b) {
            sum += a - 1;
            count++;
        }
        System.out.println(count);
    }
}
