You can play out the accompanying activity: pick some subarray (adjoining subsegment) of an and improve the components in it in any capacity you need. Yet, this activity can't be applied to the entire cluster.
For instance, if a=[2,1,4,5,3] and we need to apply the activity to the subarray a[2,4] (the subarray containing all components from the 2-nd to the 4-th), then, at that point, after the activity, the exhibit can become a=[2,5,1,4,3] or, for instance, a=[2,1,5,4,3].
Your assignment is to ascertain the base number of tasks portrayed above to sort the stage an in climbing request.
Input
The primary line contains a solitary integer t (1≤t≤2000) — the number of experiments.
The primary line of the experiment contains a solitary integer n (3≤n≤50) — the number of components in the change.
The second line of the experiment contains n particular integers from 1 to n — the given change a.
Output :For each experiment, output a solitary integer — the base number of tasks depicted above to sort the exhibit an in climbing request.
