Heap Sort Algorithm

Heap Sort Algorithm is a DSA idea you prove with next patient, not with a slogan.

Heap Sort Algorithm order — meaning → heapify + extract → one limit. Dumping ten features helps nobody.

Heap Sort Algorithm exists so Vikram can keep next patient correct in a clinic.

Vikram ships Heap Sort Algorithm in a clinic. That is the use case worth saying.

If next patient breaks under Heap Sort Algorithm, check min-heap vs max-heap mix-up first.

After Heap Sort Algorithm, Vikram should still remember min-heap vs max-heap mix-up.

One breath for Heap Sort Algorithm, then next patient, then min-heap vs max-heap mix-up. Sit down.

Exam tip

Say Heap Sort Algorithm 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]))

Heap Sort Algorithm — heap sort uses a binary heap to repeatedly extract the minimum.
