The first line contains a positive integer T(1≤T≤5), denoting the number of test cases.
For each test case:
The first line contains a positive integer n(1≤n≤2×10^5).
The second line contains n nonnegative integers x1...n(0≤xi<32677).

For each test case:
A single line contains a nonnegative integer, denoting the answer.
