Why is Binary Heap Preferred over BST for Priority Queue

Why is Binary Heap Preferred over BST for Priority Queue is a DSA topic. In plain words you use it for print jobs in a lab printer. Don’t start with a slogan — start with that picture.

Smallest example: enqueue / dequeue FIFO. Type it, run it, and say what you see. If you can do that from memory, you know Why is Binary Heap Preferred over BST for Priority Queue.

From the example next to this theory: Why is Binary Heap Preferred over BST for Priority Queue — heap sort uses a binary heap to repeatedly extract the minimum.

Trap — confusing front and rear. Fix that before you talk about advanced DSA.

Viva: what is Why is Binary Heap Preferred over BST for Priority Queue? Then show enqueue / dequeue FIFO. Then name the trap.

What is Why is Binary Heap Preferred over BST for Priority Queue? Show this: enqueue / dequeue FIFO. Trap: confusing front and rear.

Example

import heapq

def heap_sort(arr):
    h = arr[:]
    heapq.heapify(h)
    return [heapq.heappop(h) for _ in range(len(h))]

print(heap_sort([5, 1, 4, 2]))
