Problem: 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 ≠ 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 ≤ t ≤ 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 ≤ n ≤ 500) — the size of the arrays.

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

The third line containts n integers b_i (b_i ∈ \{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).

Example

Input


5
4
10 20 20 30
0 1 0 1
3
3 1 2
0 1 1
4
2 2 4 8
1 1 1 1
3
5 15 4
0 0 0
4
20 10 100 50
1 0 0 1


Output


Yes
Yes
Yes
No
Yes

Note

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 ≠ 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.

Solution (in JAVA):

Solution:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.util.StringTokenizer;

public class Problem648B {
	public static void main(String[] args) throws Exception {
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		PrintWriter writer = new PrintWriter(System.out);

		int t = Integer.parseInt(reader.readLine());
		for (int tt = 0; tt < t; tt++) {
			StringTokenizer tokenizer = new StringTokenizer(reader.readLine());
			int n = Integer.parseInt(tokenizer.nextToken());
			int[] a = new int[n];
			StringTokenizer aT = new StringTokenizer(reader.readLine());
			for (int i = 0; i < n; i++) {
				a[i] = Integer.parseInt(aT.nextToken());
			}
			int[] b = new int[n];
			StringTokenizer bT = new StringTokenizer(reader.readLine());
			for (int i = 0; i < n; i++) {
				b[i] = Integer.parseInt(bT.nextToken());
			}
			boolean allEqualType = true;
			for (int i = 0; i < n; i++) {
				if (b[i] != b[0]) {
					allEqualType = false;
					break;
				}
			}
			if (allEqualType) {
				// Enforce non decreasing
				boolean good = true;
				for (int i = 0; i < n - 1; i++) {
					if (a[i] > a[i + 1]) {
						good = false;
						break;
					}
				}
				writer.println(good ? "Yes" : "No");
			} else {
				writer.println("Yes");
			}

		reader.close();
		writer.close();
