Pythonheapqmodule 提供了堆(优先)队列的实现算法。使用 arrays,heap[k] <= heap[2k + 1];heap[k] <= heap[2k + 2],array 起始位置是 0。 参考文献: 用Python实现一个优先级队列(Priority Queue) Python 3.6 Documentation 堆Heap 堆heap,是对于每一个父结点上的值都小于或等于子结点的值的二叉树。此外...

Indeed, we have used the heap queue property to sort our list! Conclusion In this article, we learned about using the Python heapq module and saw how we could use the min-heap property to sort our unordered list. References Python Documentationon the heapq module...
