WebThe count_inversions function recursively divides the input array arr into two halves, computes the number of inversions in each half using the same count_inversions function, and then merges the two halves while also counting split inversions. The merge_and_count_inversions function is a helper function that merges two sorted … WebThus, the total number of inversions required to correctly sort the array is k*n*(n-1)/2, which in this case is 45*k. Therefore, to correctly sort the array, the user must find a total of 45*k inversions in the k trials. This is the expected number of inversions needed to correctly sort the array, and the probability of success is 1/n.
