public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
int maximum;
int number1 = Integer.parseInt(reader.readLine());
int number2 = Integer.parseInt(reader.readLine());
if (number1 > 0 && number2 > 0) {
maximum = Math.max(number1, number2);
System.out.println(maximum);
}
}
