N/A

The first line contains a single integer $ t $ ( $ 1 \le t \le 32 $ ) — the number of test cases. Each test case contains $ n $ lines. The $ i $ -th line contains an integer $ a_i $ ( $ 1 \le a_i \le 9 $ ). The sum of $ n $ over all test cases doesn't exceed $ 155 $ .

For each test case, print one integer — the answer.
