Deletion in AVL Tree

If you can teach Deletion in AVL Tree using folder on disk, you know it. If you only know the heading, you don’t.

For Deletion in AVL Tree, Big-O is in play. Don’t blame it until you have traced folder on disk.

Without Deletion in AVL Tree, a file explorer gets messy and folder on disk is hard to trust.

Use Deletion in AVL Tree when folder on disk must stay clear. If a simpler DSA step works, use that instead.

If folder on disk breaks under Deletion in AVL Tree, check unbalanced BST becoming a list first.

Deletion in AVL Tree is not a lonely heading. Sara ties it to folder on disk.

One breath for Deletion in AVL Tree, then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

For Deletion in AVL Tree: definition + a file explorer + one failure.

Example

# Deletion in AVL Tree
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Deletion in AVL Tree: dry-run [4, 1, 3]. Say the list after one step.
