import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int number = scanner.nextInt();

do {

switch (number) {

case 1:
System.out.println("Language selection");
number = scanner.nextInt();
break;

case 2:
System.out.println("Customer support");
number = scanner.nextInt();
break;

case 3:
System.out.println("Check the balance");
number = scanner.nextInt();
break;

case 4:
System.out.println("Check loan balance");
number = scanner.nextInt();
break;

}

} while(number == 1 || number == 2 || number == 3 || number == 4);
System.out.println ("Exit");

}
