题目描述

Nezzar has nn balls, numbered with integers 1,2,,n1, 2, \ldots, n . Numbers a1,a2,,ana_1, a_2, \ldots, a_n are written on them, respectively. Numbers on those balls form a non-decreasing sequence, which means that aiai+1a_i \leq a_{i+1} for all 1i<n1 \leq i < n .

Nezzar wants to color the balls using the minimum number of colors, such that the following holds.

  • For any color, numbers on balls will form a strictly increasing sequence if he keeps balls with this chosen color and discards all other balls.

Note that a sequence with the length at most 11 is considered as a strictly increasing sequence.

Please help Nezzar determine the minimum number of colors.

输入格式

The first line contains a single integer tt ( 1t1001 \le t \le 100 ) — the number of testcases.

The first line of each test case contains a single integer nn ( 1n1001 \le n \le 100 ).

The second line of each test case contains nn integers a1,a2,,ana_1,a_2,\ldots,a_n ( 1ain1 \le a_i \le n ). It is guaranteed that a1a2ana_1 \leq a_2 \leq \ldots \leq a_n .

输出格式

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

说明/提示

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][1,2,3,3,2,1] .

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