Description
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.
