Compare two approaches to Patterns—when would you choose each?

Short answer: Interviewers want a crisp definition, a practical example from your projects, and awareness of trade-offs—not textbook dumps.

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.
