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. … Web,python,data-structures,heap,recursive-datastructures,Python,Data Structures,Heap,Recursive Datastructures,Python包含用于最小堆的heapq模块，但我需要一个最大堆。Python中的max heap实现应该使用什么？最简单的方法是反转键的值并使 …
