Ashish has $n$ elements arranged in a line.

These elements are represented by two integers $a_i$ — the value of the element and $b_i$ — the type of the element (there are only two possible types: $0$ and $1$). He wants to sort the elements in non-decreasing values of $a_i$.

He can perform the following operation any number of times:

• Select any two elements $i$ and $j$ such that $b_i \ne b_j$ and swap them. That is, he can only swap two elements of different types in one move.

Tell him if he can sort the elements in non-decreasing values of $a_i$ after performing any number of operations.

Input

The first line contains one integer $t$ $(1 \le t \le 100)$ — the number of test cases. The description of the test cases follows.

The first line of each test case contains one integer $n$ $(1 \le n \le 500)$ — the size of the arrays.

The second line contains $n$ integers $a_i$ $(1 \le a_i \le 10^5)$  — the value of the $i$-th element.

The third line containts $n$ integers $b_i$ $(b_i \in \{0, 1\})$  — the type of the $i$-th element.

Output

For each test case, print "Yes" or "No" (without quotes) depending on whether it is possible to sort elements in non-decreasing order of their value.

You may print each letter in any case (upper or lower).

For the first case: The elements are already in sorted order.

For the second case: Ashish may first swap elements at positions $1$ and $2$, then swap elements at positions $2$ and $3$.

For the third case: The elements are already in sorted order.

For the fourth case: No swap operations may be performed as there is no pair of elements $i$ and $j$ such that $b_i \ne b_j$. The elements cannot be sorted.

For the fifth case: Ashish may swap elements at positions $3$ and $4$, then elements at positions $1$ and $2$.
