Conclusion – Heap sort in data structure The heap sort works internally in the binary heap, which is a completely balanced binary tree that either has the largest value or the smallest value at its node. Thus, the heapify process is carried out recursively to get the sorted array, as shown...

A New Data Structure for Heapsort with Improved Number of Comparisons (Extended Abstract)Mohammad Kaykobad
Here are two applications: keap-based PriorityQueue as a replacement of java.util.PriorityQueue and Keapsort sorting algorithm. Both might be useful in two cases: stability is a must; comparing elements is rather heavyweight operation (e.g., it requires a database access). PriorityQueue PriorityQu...

If the cache is not implemented with a LIFO approach for free lists, you need to substitute steps 2–5 with whatever algorithm is necessary to have two adjacent objects so that your victim object gets allocated once the target object has already been allocated. If allocating an object and tri...
In this tutorial, we saw an implementation of Binary Heap and Heap Sort. Even though it’s time complexity isO(n log n), in most cases, it isn’t the best algorithm on real-world data. As usual, the examples are availableover on GitHub. ...
