Given an array A of n distinct numbers, we say that a pair of numbers i, j ∈ {0, . . . , n − 1} form an inversion of A if i < j and A[i] > A[j]. Let inv(A) = {(i, j) | i < j and A[i] > A[j]}. Define the Inversion problem as follows: • Input: an array A consisting of distinct numbers. • Output: the number of inversions of A, i.e. |inv(A)|. Answer the following:...
