	Scanner sc = new Scanner(System.in);
	try {
		int n = sc.nextInt();
		for (int i = 0; i <= n - 1; i++) {
			Long number = sc.nextLong();
			if (number >= 1000000) {
				System.out.println("-1");
			}
			StringBuilder reverseIt;
			for (long j = number + 1; j < 9999999; j++) {
				reverseIt = new StringBuilder();
				reverseIt.append(j);
				if (j == Integer.parseInt((String) reverseIt.reverse().toString())) {
					System.out.println(j);
					break;
				}
			}

		}
		return;
