WebThe short answer is: heap data structure aren't binary search trees. A heap may guarantee ordering of elements in sorted top->bottom way, but a binary search tree guarantees they'll be ordered left to right as well. We were just mixing up binary trees and heaps.

WebThe heap sort technique involves the comparison that is made between the nodes, and it uses the technique of data structure called a binary heap. The heap sort works similar to the selection sort, where we find the smallest element and then the smallest element is placed at the beginning. WebIn a nutshell, their solution is to have each element in the heapq be a triple with the priority, an entry count and the element to be inserted. The entry count ensures that elements with the same priority a sorted in the order they were added to the heapq. Share Improve this answer Follow answered Jan 16, 2012 at 4:37 srgerg 18.5k 4 56 39
