## Problem Statement

#### Example:

``````We have an array ARR = {1, 2, 3, 4, 5, 6} and M = 3 , considering 0
based indexing so the subarray {5, 6} will be reversed and our
output array will be {1, 2, 3, 4, 6, 5}.
``````
Detailed explanation ( Input/output format, Notes, Images )
##### Constraints:
``````1 <= T <= 10
0 <= M <= N <= 5*10^4
-10^9 <= ARR[i] <= 10^9

Time Limit: 1 sec
``````
##### Sample Input 1:
``````2
6 3
1 2 3 4 5 6
5 2
10 9 8 7 6
``````
##### Sample Output 1:
``````1 2 3 4 6 5
10 9 8 6 7
``````
##### Explanation 1:
``````For the first test case,
Considering 0-based indexing we have M = 3 so the
subarray[M+1 β¦ N-1] has to be reversed.
Therefore the required output will be {1, 2, 3, 4, 6, 5}.

For the second test case,
Considering 0-based indexing we have M = 2 so the
subarray[M+1 β¦ N-1] has to be reversed.
Therefore the required output will be {10, 9, 8, 6, 7}.
``````
##### Sample Input 2:
``````2
7 3
1 4 5 6 6 7 7
9 3
10 4 5 2 3 6 1 3 6
``````
##### Sample Output 2:
`````` 1 4 5 6 7 7 6
10 4 5 2 6 3 1 6 3
``````
