java Data Structures and Algorithms Given an array of n distinct numbers

Given an array of n distinct numbers (a1, a2, ..., an], we define the number of out-of-order pairs (OOOPs) as the number of pairs (aj, aj) (0 aj. For example, the array [1, 6, 2, 8] has 1 OOOP (6,2). Array (5, 4, 3, 0] on the other hand has (5, 4), (5, 3), (5,0), (4,3), (4, 0), and (3, 0) for a total of 6 OOOPs. Given an array A. write the most efficient function possible to find the number of OOOPs in that array. For example: Test Input Result how_many_000PS (arr) [1, 6, 2, 8] 1 how_many_000Ps (arr) [5, 4, 3, 0] 6
