MO's Algorithm

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

Smallest example: the smallest MO's Algorithm example you can type. Type it, run it, and say what you see. If you can do that from memory, you know MO's Algorithm.

From the example next to this theory — MO's Algorithm: dry-run [4, 1, 3].

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

Viva — what is MO's Algorithm? Then show the smallest MO's Algorithm example you can type. Then name the trap.
