Gildong needs to make all components of an equivalent — he will consistently do as such utilizing the base number of activities important. To make his life much more straightforward, before Gildong begins utilizing the machine, you have the choice of transforming one of the integers in the cluster to some other integer. You are permitted to leave the cluster unaltered. You need to limit the number of activities Gildong performs. With your assistance, what is the base number of activities Gildong will perform?
Note that regardless of whether you change one of the integers in the cluster, you ought not consider that one of the activities on the grounds that Gildong didn't perform it.
Input
Each test contains at least one experiments. The main line contains the number of experiments t (1≤t≤1000).
Each experiment contains two lines. The primary line of each experiment comprises of an integer n (2≤n≤2⋅105) — the number of components of the exhibit a.
The second line of each experiment contains n integers. The I-th integer is man-made intelligence (−5⋅108≤ai≤5⋅108).
It is ensured that the amount of n in all experiments doesn't surpass 2⋅105.
Output
For each experiment, print one integer — the base number of activities Gildong needs to act to make all components of the exhibit equivalent.
