Showstopper
You are given two arrays and .
In one operation, you can choose any integer from to and swap the numbers and .
Determine whether, after using any (possibly zero) number of operations, the following two conditions can be satisfied simultaneously:
- ,
- .
Here denotes the maximum number among . For example, , , .
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The first line of each test case contains a single integer () — the length of the arrays.
The second line of each test case contains integers () — elements of the first array.
The third line of each test case contains integers () — elements of the second array.
Output
For each test case, print "Yes" if after using any (possibly zero) number of operations the conditions described above are satisfied. Otherwise, print "No".
You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.
Note
In the first test case, you can swap the numbers and , after which the array becomes equal to , and the array becomes equal to , and both conditions are met.
In the second test case, it can be proved that it is impossible to satisfy both conditions.
In the third test case, you can swap the numbers and , after which the array becomes equal to , and the array becomes equal to , and both conditions are satisfied.
In fifth test case, you can swap and , and , and , after which the array becomes equal to , and the array becomes equal to , and both conditions are satisfied.
