Complex Data Structures

Complex Data Structures is a DSA topic. In plain words you use it for n vs n² on 10k rows in a viva. Don’t start with a slogan — start with that picture.

Smallest example: best / average / worst + extra memory. Type it, run it, and say what you see. If you can do that from memory, you know Complex Data Structures.

From the example next to this theory — Complex Data Structures: dry-run [4, 1, 3].

Trap — saying ‘fast’ with no Big-O. Fix that before you talk about advanced DSA.

Viva — what is Complex Data Structures? Then show best / average / worst + extra memory. Then name the trap.
