import java.util.Scanner;
//0xAA 中0x是16进制标识，在做进制转化的时候要将前两位去掉，用substring做字符串截取
public class Main{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
while(sc.hasNextLine()){
String str = sc.nextLine();
int answer = Integer.parseInt(str.substring(2),16);
System.out.println(answer);
}
