Inversion count

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

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

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

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

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