    I saw a lot of solutions here that are wrong. I do not know why the test cases do not catch it. One example where most of solutions will fail is for an input of 10 and 7. I hope the test cases are updated.

    A complete correct solution.

    import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int p = in.nextInt();
        
        int s = p/2;
        
        int f = n%2==0 ? (n+1-p)/2 : (n-p)/2 ;
        
        int b = s<f ? s : f;
        
        System.out.println(b);
        
        
        // your code goes here
    }
}
