What's the relationship between a heap and the heap

What's the relationship between a heap and the heap sits in a clinic. Dev’s job is next patient. Write that first.

Do What's the relationship between a heap and the heap once by hand. heapify + extract. Change one input. Say the new result out loud.

What's the relationship between a heap and the heap exists so Dev can keep next patient correct in a clinic.

Use What's the relationship between a heap and the heap when next patient must stay clear. If a simpler DSA step works, use that instead.

What's the relationship between a heap and the heap miss: min-heap vs max-heap mix-up. Fix it before you talk about advanced DSA.

What's the relationship between a heap and the heap is not a lonely heading. Dev ties it to next patient.

Close What's the relationship between a heap and the heap with: “If I skip it, next patient goes wrong like this: min-heap vs max-heap mix-up.”

Exam tip

Say What's the relationship between a heap and the heap in one breath, then heapify + extract, then min-heap vs max-heap mix-up.

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]))

What's the relationship between a heap and the heap — heap sort uses a binary heap to repeatedly extract the minimum.
