Real-world example (ShopNest)

Walk through a small ShopNest-sized input (cart lines, order ids), then state time and space complexity.

Say this in the interview

  1. Define — one clear sentence (the short answer above).
  2. Example — relate it to a project like ShopNest or your real work.
  3. Trade-off — when you would not use it.
