Description

Input

The first line contains a single integer $t$ ($1 \le t \le 100$) — the number of testcases.

The first line of each test case contains a single integer $n$ ($1 \le n \le 100$).

The second line of each test case contains $n$ integers $a_1,a_2,\ldots,a_n$ ($1 \le a_i \le n$). It is guaranteed that $a_1 \leq a_2 \leq \ldots \leq a_n$.

Output

For each test case, output the minimum number of colors Nezzar can use.

Note

Let's match each color with some numbers. Then:

In the first test case, one optimal color assignment is $[1,2,3,3,2,1]$.

In the second test case, one optimal color assignment is $[1,2,1,2,1]$.
