General Tree (Each node can have arbitrary number of children) Level Order Traversal

General Tree (Each node can have arbitrary number of children) Level Order Traversal sits in a file explorer. Neha’s job is folder on disk. Write that first.

For General Tree (Each node can have arbitrary number of children) Level Order Traversal, time vs memory is in play. Don’t blame it until you have traced folder on disk.

Skip General Tree (Each node can have arbitrary number of children) Level Order Traversal and unbalanced BST becoming a list shows up in a file explorer.

Use General Tree (Each node can have arbitrary number of children) Level Order Traversal when folder on disk must stay clear. If a simpler DSA step works, use that instead.

Don’t do this with General Tree (Each node can have arbitrary number of children) Level Order Traversal: unbalanced BST becoming a list. Interviewers spot it in ten seconds.

Place General Tree (Each node can have arbitrary number of children) Level Order Traversal next to nearby DSA work — left < root < right is the link.

Viva for General Tree (Each node can have arbitrary number of children) Level Order Traversal: what it is → left < root < right → the mistake (unbalanced BST becoming a list).

Exam tip

For General Tree (Each node can have arbitrary number of children) Level Order Traversal: definition + a file explorer + one failure.

Example

# General Tree (Each node can have arbitrary number of children) Level Order Traversal
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)

General Tree (Each node can have arbitrary number of children) Level Order Traversal: dry-run [4, 1, 3]. Say the list after one step.
