WebThe heapsort algorithm is divided into two parts. In the first part, the heap tree is built and in the second step the array is sorted by removing the largest element from the array repeatedly and inserting it at its sorted position and after that, the heap tree is created again. WebBuilding a heap from array makes sure that heap order property is maintained after every input. The input is checked if it is greater than it’s parent, if it’s not, it is swapped. In an array, the element at each node occupies an index in the array. For example, a node containing element 6 occupies index = 3 in the array.
