Difference between Min Heap and Max Heap

Difference between Min Heap and Max Heap is a DSA topic. In plain words you use it for next patient in a clinic. Don’t start with a slogan — start with that picture.

Smallest example: heapify + extract. Type it, run it, and say what you see. If you can do that from memory, you know Difference between Min Heap and Max Heap.

From the example next to this theory: Difference between Min Heap and Max Heap — heap sort uses a binary heap to repeatedly extract the minimum.

Trap — min-heap vs max-heap mix-up. Fix that before you talk about advanced DSA.

Viva — what is Difference between Min Heap and Max Heap? Then show heapify + extract. Then name the trap.

Exam tip

What is Difference between Min Heap and Max Heap? Show this: heapify + extract. Trap: 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]))

Difference between Min Heap and Max Heap — heap sort uses a binary heap to repeatedly extract the minimum.
