5.When does the worst case for heap sort happen? write in your answer script.
COUNT = 0 Sort(arr, left, right): if left > right return mid = (left+right)/2 Sort(arr, left, mid) Sort(arr, mid+1, right) partition(arr, left, mid, right) end partition(arr, left, mid, right): //creating temporary array based on mid index A[]= arr[left:mid] B[]= arr[mid:right] n1 = length[A], n2 = length[B], n = n1 + n2 Create C[1 .. n] Initialize two indices i,j to point to A and B while i< n1 and j do Select the smaller of Alil.Blil and add to end of C < n2
