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.
