##### Submissions: 2396   Accuracy: 58.55%   Difficulty: Basic   Marks: 1

Construct an N input AND Gate. An AND Gate returns 1 if all its inputs are 1, otherwise 0.

Input:

The first line of input takes the number of test cases, T. Then T test cases follow.

Each test case consists of 2 lines.

The first line of each test case takes the number of inputs to the AND Gate, N. The second line of each test case takes N space separated integers denoting the inputs to the  AND Gate. Note that the inputs can be either 1's or 0's.

Output:

Print the output of the N input AND Gate for each test case on a new line.

Constraints:

1<=T<=100

1<=N<=100

Example:

Input:

3
2
1 1
3
1 0 1
4
1 1 1 0

Output:

```1
0
0```
