Deletion at beginning

Deletion at beginning (cll) is a DSA topic. In plain words you use it for a short Deletion at beginning cll example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Deletion at beginning cll example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Deletion at beginning (cll).

From the example next to this theory — Deletion at beginning (cll) — Dry-run [4, 1, 3].

Trap — only saying “Deletion at beginning cll” with no example. Fix that before you talk about advanced DSA.

Viva: what is Deletion at beginning (cll)? Then show the smallest Deletion at beginning cll example you can type. Then name the trap.
