import java.util.Scanner;
// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String x = in.nextLine();
String[] result = x.split(",");
long b = Long.parseLong(result[3]);
long a = Integer.parseInt(result[1]);
long out = b - a -1;
System.out.print(out);
}
}
注:应使用Long.parseLong()避免NumberFormatException问题
