Consider an array that is to be sorted using heap sort. The steps we follow during heap sort are:- Initially build a max heap of elements in Arr. The root element contains the maximum element i.e. Arr[0]. So swap that element will last element of the heap and then heapify the heap...
The main breaking change is that nowtop(N)does NOT sort the output, because sorting should not be part of the spec for a priority queue. The output is the top N elements, and they will bepartially orderedwith the peek at index0by definition. ...
heapSortAlgo(arr, n); cout << "Using heap sort the generated sorted array is \n"; display(arr, n); } The output of the execution of the above program in C++ language is as shown below – Time complexity The time complexity of the heap sort is O(nlogn). On the other hand, when...
Example of Heap Sort in C++ This technique uses binary heap which is constructed using a complete binary tree where the root node is greater than its two children nodes. Consider the given array of data sets. Let us go according to the algorithm. It says to select the highest element as ...
