Diameter of an N-ary tree

Diameter of an N-ary tree (alt) sits in a file explorer. Vikram’s job is folder on disk. Write that first.

Keep Diameter of an N-ary tree (alt) small. Vikram should finish folder on disk in a few lines, not a 40-line dump.

Diameter of an N-ary tree (alt) exists so Vikram can keep folder on disk correct in a file explorer.

Vikram ships Diameter of an N-ary tree (alt) in a file explorer. That is the use case worth saying.

If folder on disk breaks under Diameter of an N-ary tree (alt), check unbalanced BST becoming a list first.

Diameter of an N-ary tree (alt) is not a lonely heading. Vikram ties it to folder on disk.

One breath for Diameter of an N-ary tree (alt), then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

Say Diameter of an N-ary tree (alt) in one breath, then left < root < right, then unbalanced BST becoming a list.

Example

# Diameter of an N-ary 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)

Diameter of an N-ary tree (alt) — Dry-run [4, 1, 3]. Say the list after one step.

Short notes

DefDiameter of an N-ary tree (alt) — Vikram uses it for folder on disk in a file explorer.
