Black is gifted with a Divine array $$$a$$$ consisting of $$$n$$$ ($$$1 \le n \le 2000$$$) integers. Each position in $$$a$$$ has an initial value. After shouting a curse over the array, it becomes angry and starts an unstoppable transformation.

The transformation consists of infinite steps. Array $$$a$$$ changes at the $$$i$$$-th step in the following way: for every position $$$j$$$, $$$a_j$$$ becomes equal to the number of occurrences of $$$a_j$$$ in $$$a$$$ before starting this step.

Here is an example to help you understand the process better:

Initial array:	$$$2$$$ $$$1$$$ $$$1$$$ $$$4$$$ $$$3$$$ $$$1$$$ $$$2$$$
After the $$$1$$$-st step:	$$$2$$$ $$$3$$$ $$$3$$$ $$$1$$$ $$$1$$$ $$$3$$$ $$$2$$$
After the $$$2$$$-nd step:	$$$2$$$ $$$3$$$ $$$3$$$ $$$2$$$ $$$2$$$ $$$3$$$ $$$2$$$
After the $$$3$$$-rd step:	$$$4$$$ $$$3$$$ $$$3$$$ $$$4$$$ $$$4$$$ $$$3$$$ $$$4$$$
...	...

In the initial array, we had two $$$2$$$-s, three $$$1$$$-s, only one $$$4$$$ and only one $$$3$$$, so after the first step, each element became equal to the number of its occurrences in the initial array: all twos changed to $$$2$$$, all ones changed to $$$3$$$, four changed to $$$1$$$ and three changed to $$$1$$$.

The transformation steps continue forever.

You have to process $$$q$$$ queries: in each query, Black is curious to know the value of $$$a_x$$$ after the $$$k$$$-th step of transformation.

Input

Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$1 \le t \le 1000$$$). Description of the test cases follows.

The first line of each test case contains an integer $$$n$$$ ($$$1 \le n \le 2000$$$) — the size of the array $$$a$$$.

The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le n$$$) — the initial values of array $$$a$$$.

The third line of each test case contains a single integer $$$q$$$ ($$$1 \le q \le 100\,000$$$) — the number of queries.

Next $$$q$$$ lines contain the information about queries — one query per line. The $$$i$$$-th line contains two integers $$$x_i$$$ and $$$k_i$$$ ($$$1 \le x_i \le n$$$; $$$0 \le k_i \le 10^9$$$), meaning that Black is asking for the value of $$$a_{x_i}$$$ after the $$$k_i$$$-th step of transformation. $$$k_i = 0$$$ means that Black is interested in values of the initial array.

It is guaranteed that the sum of $$$n$$$ over all test cases doesn't exceed $$$2000$$$ and the sum of $$$q$$$ over all test cases doesn't exceed $$$100\,000$$$.

Output

For each test case, print $$$q$$$ answers. The $$$i$$$-th of them should be the value of $$$a_{x_i}$$$ after the $$$k_i$$$-th step of transformation. It can be shown that the answer to each query is unique.

Note

The first test case was described ih the statement. It can be seen that:

$$$k_1 = 0$$$ (initial array): $$$a_3 = 1$$$;
$$$k_2 = 1$$$ (after the $$$1$$$-st step): $$$a_1 = 2$$$;
$$$k_3 = 2$$$ (after the $$$2$$$-nd step): $$$a_2 = 3$$$;
$$$k_4 = 1$$$ (after the $$$1$$$-st step): $$$a_6 = 3$$$.

For the second test case,

Initial array:	$$$1$$$ $$$1$$$
After the $$$1$$$-st step:	$$$2$$$ $$$2$$$
After the $$$2$$$-nd step:	$$$2$$$ $$$2$$$
...	...

It can be seen that:

$$$k_1 = 0$$$ (initial array): $$$a_1 = 1$$$;
$$$k_2 = 1000000000$$$: $$$a_2 = 2$$$;
