Handshaking Lemma and Interesting Tree Properties

Handshaking Lemma and Interesting Tree Properties is simple if you keep it on paper. Asha uses it for folder on disk in a file explorer.

Do Handshaking Lemma and Interesting Tree Properties once by hand. left < root < right. Change one input. Say the new result out loud.

Without Handshaking Lemma and Interesting Tree Properties, a file explorer gets messy and folder on disk is hard to trust.

Handshaking Lemma and Interesting Tree Properties shows up in a file explorer. Name folder on disk, not “a real-world scenario”.

If folder on disk breaks under Handshaking Lemma and Interesting Tree Properties, check unbalanced BST becoming a list first.

After Handshaking Lemma and Interesting Tree Properties, Asha should still remember unbalanced BST becoming a list.

Viva for Handshaking Lemma and Interesting Tree Properties: what it is → left < root < right → the mistake (unbalanced BST becoming a list).

Exam tip

For Handshaking Lemma and Interesting Tree Properties: definition + a file explorer + one failure.

Example

# Handshaking Lemma and Interesting Tree Properties
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)

Handshaking Lemma and Interesting Tree Properties: dry-run [4, 1, 3]. Say the list after one step.
