instance, in the event that n=6 and a=[1,3,2,1,4,2], the accompanying choices are feasible to make the exhibit a cluster excellent: Polycarp eliminates components at positions 2 and 5, exhibit a becomes equivalent to [1,2,1,2];
Correct answer will be upvoted else downvoted. Computer science.
For instance, in the event that n=6 and a=[1,3,2,1,4,2], the accompanying choices are feasible to make the exhibit a cluster excellent:
Polycarp eliminates components at positions 2 and 5, exhibit a becomes equivalent to [1,2,1,2];
Polycarp eliminates components at positions 1 and 6, cluster a becomes equivalent to [3,2,1,4];
Polycarp eliminates components at positions 1,2 and 6, cluster a becomes equivalent to [2,1,4];
Assist Polycarp with deciding the base number of components to eliminate from the cluster a to make it lovely.
Input
The primary line contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t experiments follow.
The main line of each experiment comprises of one integer n (1≤n≤2⋅105) — the length of the exhibit a.
The second line of each experiment contains n integers a1,a2,… ,an (1≤
It is ensured that the amount of n over all experiments doesn't surpass 2⋅105.
Output
For each experiment, output one integer — the base number of components that Polycarp needs to eliminate from the cluster a to make it delightful.
