WebOverview. The heapsort algorithm can be divided into two parts. In the first step, a heap is built out of the data (see Binary heap § Building a heap).The heap is often placed in an array with the layout of a complete binary tree.The complete binary tree maps the binary tree structure into the array indices; each array index represents a node; the index of the … WebHeapsort in Java is a comparison based sorting technique, where data structure Binary Heap is used. This sorting is almost the same as that of selection sort, where the largest element will be selected, and places in the end, and the …

WebThe first loop, the Θ (n) “heapify” phase, puts the array into heap order. The second loop, the O (n·lg (n)) “sortdown” phase, repeatedly extracts the maximum and restores heap order. The sink function is written recursively for clarity. Thus, as shown, the code requires Θ (lg (n)) space for the recursive call stack.
