Pre-order Traversal
Pre-order Traversal is a DSA topic. In plain words you use it for a short Pre-order Traversal example in a short dry-run on paper. Don’t start with a slogan — start with that picture.
Smallest example: the smallest Pre-order Traversal example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Pre-order Traversal.
From the example next to this theory — Pre-order Traversal: dry-run [4, 1, 3].
Trap — only saying “Pre-order Traversal” with no example. Fix that before you talk about advanced DSA.
Viva — what is Pre-order Traversal? Then show the smallest Pre-order Traversal example you can type. Then name the trap.
What is Pre-order Traversal? Show this: the smallest Pre-order Traversal example you can type. Trap: only saying “Pre-order Traversal” with no example.
