AVL Tree Applications

Don’t start AVL Tree Applications with jargon. Start with folder on disk. That is the whole point.

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

AVL Tree Applications exists so Kabir can keep folder on disk correct in a file explorer.

Kabir ships AVL Tree Applications in a file explorer. That is the use case worth saying.

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

Place AVL Tree Applications next to nearby DSA work — left < root < right is the link.

Close AVL Tree Applications with — “If I skip it, folder on disk goes wrong like this: unbalanced BST becoming a list.”

Exam tip

Say AVL Tree Applications in one breath, then left < root < right, then unbalanced BST becoming a list.

Example

# AVL Tree Applications
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)

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