Correct answer will be upvoted else downvoted. Computer science.
you select two distinct numbers in the cluster
you eliminate I-th and j-th components from the cluster.
For instance, on the off chance that n=6 and a=[1,6,1,1,4,4], you can play out the accompanying arrangement of activities:
select i=1,j=5. The cluster a becomes equivalent to [6,1,1,4];
select i=1,j=2. The cluster a becomes equivalent to [1,4].
What can be the base size of the cluster in the wake of applying some grouping of tasks to it?
Input
The primary line contains a solitary integer t (1≤t≤104). Then, at that point, t experiments follow.
The principal line of each experiment contains a solitary integer n (1≤n≤2⋅105) is length of the exhibit a.
The second line of each experiment contains n integers a1,a2,… ,an (1≤ai≤109).
It is ensured that the amount of n over all experiments doesn't surpass 2⋅105.
Output
For each experiment, output the base conceivable size of the cluster in the wake of applying some grouping of tasks to it.
