public static void main(String[] args) throws Exception {
//tutaj wpisz swój kod
BufferedReader reader = new BufferedReader (new InputStreamReader(System.in));
String pierwsza = reader.readLine();
String druga = reader.readLine();
String trzecia = reader.readLine();
int a = Integer.parseInt(pierwsza);
int b = Integer.parseInt(druga);
int c = Integer.parseInt(trzecia);
if (a==b && a!=c)
{
System.out.println(c);
}
if (a==c && a!=b)
{
System.out.println(b);
}
if (c==b && b!=a)
{
System.out.println(a);
