Smallest example: n log n vs n². Type it, run it, and say what you see. If you can do that from memory, you know Internal Sorting (what is).

Trap — unstable sort when equal keys matter. Fix that before you talk about advanced DSA.

Viva — what is Internal Sorting (what is)? Then show n log n vs n². Then name the trap.
