public class Main {
    static int parseOrDefault(String s) {
        try {
            return Integer.parseInt(s);
        } catch (NumberFormatException e) {
            return -1;
        } finally {
            System.out.println("checked " + s);
        }
    }

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for (int i = 0; i < n; i++) {
            System.out.println(parseOrDefault(sc.next()));
        }
    }
}
