LIFO Approach

LIFO Approach is a DSA topic. In plain words you use it for a short LIFO Approach example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest LIFO Approach example you can type. Type it, run it, and say what you see. If you can do that from memory, you know LIFO Approach.

From the example next to this theory — LIFO Approach: dry-run [4, 1, 3].

Trap — only saying “LIFO Approach” with no example. Fix that before you talk about advanced DSA.

Viva — what is LIFO Approach? Then show the smallest LIFO Approach example you can type. Then name the trap.
