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.

import java.util.Collections;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        int problemCount = scanner.nextInt();

            ArrayList<Integer> numberList = new ArrayList<>();
            ArrayList<Integer> zeroOneList = new ArrayList<>();
            ArrayList<Integer> sortedNumberList = new ArrayList<>();

            String[] numberArray = scanner.nextLine().split(" ");
            String[] bNumberArray = scanner.nextLine().split(" ");

            for (int i = 0; i < numberArray.length; i++) {
                numberList.add(Integer.parseInt(numberArray[i]));
                sortedNumberList.add(Integer.parseInt(numberArray[i]));
            }

            int oneCount=0;
            int zeroCount=0;

            for (int i = 0; i < bNumberArray.length; i++) {

                if(Integer.parseInt(bNumberArray[i])==0){
                    zeroCount+=1;
                }
                else {
                    oneCount+=1;
                }
                zeroOneList.add(Integer.parseInt(bNumberArray[i]));
            }

            ourProblemCount += 1;
            Collections.sort(sortedNumberList);

            if(sortedNumberList.equals(numberList)){
                System.out.println("Yes");
            }
            else if(oneCount==0||zeroCount==0){
