Question: Let A[1, .., n] be an array of n distinct numbers. If i A[j], then the pair (i, j) is called an inversion of A.

Let A[1, .., n] be an array of n distinct numbers.

Let A[1, .., n] be an array of n distinct numbers. If i A[j], then the pair (i, j) is called an inversion of A. a. List the five inversions of the array [2, 3, 8, 6, 1] b. What array with elements from the set {1, 2, .., n} has the move inversions? How many does it have? Write an algorithm that determined the number of inversions in any array containing n numbers in Theta(nlg n) worse-case time
