Priority Queues (Heaps)

Priority Queues (Heaps). Priority Queues. Many applications require that we process records with keys in order, but not necessarily in full sorted order. Often we collect a set of items and process the one with the current minimum value. e.g. jobs sent to a printer,

Heapsort and d-Heap Neil Tang 02/11/2010

Heapsort and d-Heap Neil Tang 02/11/2010. Class Overview. d-Heap Sort using a heap Heapsort. d-Heap. A d-Heap is exactly like a binary heap except that all the nodes have no more than d children. d-Heap. Insertion takes O(log d N). deleteMin takes O(dlog d N)
