public class Main{

	public static void main(String[] args) {

		Scanner scanner = new Scanner(System.in);
		int t = scanner.nextInt();
		BigInteger sum ;
		for (int i = 1; i <= t; i++) {
			sum = BigInteger.ZERO;
			while (true) {
				BigInteger num = scanner.nextBigInteger();
				if (num.equals(BigInteger.ZERO)) {
					break;
				} else {
					sum = sum.add(num);
				}
			}
			System.out.println(sum);
			if (i != t) {
