CF1637A.Sorting Parts
Sorting Parts
You have an array of length . You can exactly once select an integer between and inclusively, and then sort in non-decreasing order the prefix of the array of length and the suffix of the array of length independently.
For example, if the array is , and you choose , then after that the array will be equal to .
Could it be that after performing this operation, the array will not be sorted in non-decreasing order?
Input
There are several test cases in the input data. The first line contains a single integer () — the number of test cases. This is followed by the test cases description.
The first line of each test case contains one integer () — the length of the array.
The second line of the test case contains a sequence of integers () — the array elements.
It is guaranteed that the sum of over all test cases does not exceed .
Output
For each test case of input data, output "YES" (without quotes), if the array may be not sorted in non-decreasing order, output "NO" (without quotes) otherwise. You can output each letter in any case (uppercase or lowercase).
Note
In the first test case, it's possible to select , then after operation, the array will not be sorted in non-decreasing order and will be equal to .
In the second test case, it's possible to select , then after operation, the array will not be sorted in non-decreasing order and will be equal to .
In the third test case, the array will be sorted in non-decreasing order for every possible .
