 Guess permutation from number of inverted (unordered) pairs
 Maximum can be found
 
 Find the minimum element by placing them at the start, then querying
 n(n+1)/2 queries; satisfies ST2
 
 Swap a block to know how many in one are less than the other
 
 O(n log n) sort?
 Score of x 1 2 ... N-2 N-1 N = score of original - sum(a_i>a_x) + sum(a_i<a_x)
 sum(a_i>a_x) + sum(a_i<a_x) = x (quicksort-like comparison)
 (newscore-curscore+x)/2
 
 Already sorted a region; query
 
 2n-2 solution; This gives 70? points
 
 Next score can be computed as score of original - sum(a_i>a_x)
 This has a count of N
