Recaman's Sequence

Recaman's Sequence (alt) is a DSA topic. In plain words you use it for a short Recaman's Sequence alt example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Recaman's Sequence alt example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Recaman's Sequence (alt).

From the example next to this theory — Recaman's Sequence (alt) — Dry-run [4, 1, 3].

Trap — only saying “Recaman's Sequence alt” with no example. Fix that before you talk about advanced DSA.

Viva: what is Recaman's Sequence (alt)? Then show the smallest Recaman's Sequence alt example you can type. Then name the trap.
