"WebJan 18, 2024 · So what is Heap sort? Well, heaps are of two type max heap and min heap. The Basic and important rule to follow is that in a max heap the parent node should be greater than that of its child. In the example given above the node 8 is greater than its parent, so we move it up till every node is satisfying the rule. " - How does heap sort work

WebMar 18, 2012 · If built from the bottom up, insertion (heapify) can be much less than O (log (n)). The process is as follows: ( Step 1 ) The first n/2 elements go on the bottom row of the heap. h=0, so heapify is not needed. ( Step 2 ) The next n/2 2 elements go on the row 1 up from the bottom. h=1, heapify filters 1 level down. WebDec 21, 2024 · Heap sort is a comparison-based sorting technique based on Binary Heap data structure.

It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The most important variation to the basic algorithm, which is included in all practical implementations, is a heap-construction algorithm by Floyd which runs in O(n) time and uses siftdown rather than siftup, avoiding the need to implement siftup at all. Rather than starting with a trivial heap and repeatedly adding leaves, Floyd's algorithm starts with the leaves, observing that they are trivial but valid heaps by themselves, and then adds parents. …
