Heap Sort - javatpoint

WebThe best case input is an array that is already sorted. In this case insertion sort has a linear running time (i.e., O(n)). During each iteration, the first remaining element of the input is only compared with the right-most element of the sorted subsection of the array. The simplest worst case input is an array sorted in reverse order. WebNow, the worst case will occur if the inserted value had to be shifted until we reached the root, which means the value is greatest or smallest for MaxHeap and MinHeap respectively. And since, to reach the root we will be going to go through one parent on each level and since, there are logN levels.
