Flyweight (Character):?

Short answer: This class represents the Flyweight object. It contains the intrinsic state that is shared across multiple instances (the character symbol, in this case), and it provides a Display method to show the character's symbol at a particular coordinate. public class Character

Example code

{
private readonly char _symbol;
public Character(char symbol) => _symbol = symbol;
public void Display(int x, int y) => Console.WriteLine($"Character: {_symbol} at ({x}, {y})"); }

Real-world example (ShopNest)

Use a GoF pattern in ShopNest only when it removes duplication or makes a change safer—explain the problem it solves in the interview.

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.
