Beautiful Subsequence SOLUTIONS CHEFHALF

Think about an arrangement with an even length 2L. A left pivot comprises of moving the main component of the succession as far as possible. The arrangement is acceptable in the event that it is conceivable to play out some number of left pivots (potentially zero) and gap the subsequent succession into equal parts (containing the main L and keep going L components individually) with the end goal that the littlest incentive in one half is more prominent then the biggest incentive in the other half. 

You are given a succession A1,A2,… ,AN. Locate the quantity of itas non-void adjoining aftereffects with even length which is acceptable. 



The main line of the info contains a solitary number T signifying the quantity of experiments. The portrayal of T experiments follows. 

The main line of each experiment contains a solitary number N. 

The subsequent line contains N space-isolated whole numbers A1,A2,… ,AN. 



For each experiment, print a solitary line containing one whole number ― the quantity of good coterminous aftereffects. 





1≤Ai≤109 for each legitimate I 

A1,A2,… ,AN are pair-wise unmistakable 

the aggregate of N over all experiments doesn’t surpass 106 


Model Input 

1 2 3 4 

4 2 1 3 

1 3 2 4 


Model Output 



Model case 1: The great aftereffects are [1,2], [2,3], [3,4] and [1,2,3,4]. 

Model case 3: The great aftereffects are [1,3], [3,2] and [2,4].
