An integer array $a_1, a_2, \ldots, a_n$ is being transformed into an array of lowercase English letters using the following prodecure:

While there is at least one number in the array:

Choose any number $x$ from the array $a$, and any letter of the English alphabet $y$.

Replace all occurrences of number $x$ with the letter $y$.

For example, if we initially had an array $a = [2, 3, 2, 4, 1]$, then we could transform it the following way:

Choose the number $2$ and the letter c. After that $a = [c, 3, c, 4, 1]$.

Choose the number $3$ and the letter a. After that $a = [c, a, c, 4, 1]$.

Choose the number $4$ and the letter t. After that $a = [c, a, c, t, 1]$.

Choose the number $1$ and the letter a. After that $a = [c, a, c, t, a]$.

After the transformation all letters are united into a string, in our example we get the string "cacta".

Having the array $a$ and the string $s$ determine if the string $s$ could be got from the array $a$ after the described transformation?


-----Input-----

The first line contains a single integer $t$ $(1 \leq t \leq 10^3$) — the number of test cases.

Then the description of the test cases follows.

The first line of each test case contains a single integer $n$ ($1 \leq n \leq 50$) — the length of the array $a$ and the string $s$.

The second line of each test case contains exactly $n$ integers: $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 50$) — the elements of the array $a$.

The third line of each test case contains a string $s$ of length $n$, consisting of lowercase English letters.


-----Output-----

For each test case, output "YES", if we can get the string $s$ from the array $a$, and "NO" otherwise. You can output each letter in any case.


-----Examples-----

Input
7
5
2 3 2 4 1
cacta
1
50
a
2
11 22
ab
4
1 2 2 1
aaab
5
1 2 3 2 1
aaaaa
6
1 10 2 9 3 8
azzfdb
7
1 2 3 4 1 1 2
abababb
Output
YES
YES
YES
NO
YES
YES
NO


-----Note-----

The first test case corresponds to the sample described in the statement.

In the second test case we can choose the number $50$ and the letter a.

In the third test case we can choose the number $11$ and the letter a, after that $a = [a, 22]$. Then we choose the number $22$ and the letter b and get $a = [a, b]$.

In the fifth test case we can change all numbers one by one to the letter a.
