Application of heap tree

Application of heap tree is simple if you keep it on paper. Meera uses it for folder on disk in a file explorer.

Do Application of heap tree once by hand. left < root < right. Change one input. Say the new result out loud.

Application of heap tree exists so Meera can keep folder on disk correct in a file explorer.

Use Application of heap tree when folder on disk must stay clear. If a simpler DSA step works, use that instead.

Application of heap tree miss — unbalanced BST becoming a list. Fix it before you talk about advanced DSA.

Place Application of heap tree next to nearby DSA work — left < root < right is the link.

One breath for Application of heap tree, then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

Board: folder on disk. Dry-run Application of heap tree. Name the trap: unbalanced BST becoming a list.

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]))

Application of heap tree — heap sort uses a binary heap to repeatedly extract the minimum.

Short notes
