Ternary Search Tree

Ternary Search Tree sits in a file explorer. Kabir’s job is folder on disk. Write that first.

For Ternary Search Tree, time vs memory is in play. Don’t blame it until you have traced folder on disk.

Skip Ternary Search Tree and unbalanced BST becoming a list shows up in a file explorer.

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

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

After Ternary Search Tree, Kabir should still remember unbalanced BST becoming a list.

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

Exam tip

For Ternary Search Tree: definition + a file explorer + one failure.

Example

# Ternary Search 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)

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