Insertion in AVL Tree

Priya only reaches for Insertion in AVL Tree when folder on disk has to stay correct in a file explorer.

Insertion in AVL Tree on the board — left < root < right. Then say what folder on disk looks like after.

Insertion in AVL Tree exists so Priya can keep folder on disk correct in a file explorer.

Insertion in AVL Tree shows up in a file explorer. Name folder on disk, not “a real-world scenario”.

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

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

Viva for Insertion in AVL Tree — what it is → left < root < right → the mistake (unbalanced BST becoming a list).

Exam tip

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

Example

# Insertion 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)

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