LLD - Advanced LLD Concepts

AMagic Numbers; it uses unexplained constants

BGod Object; it centralizes all logic in one place

CShotgun Surgery; it requires many changes for one feature

DSwitch Statements Anti-pattern; it reduces extensibility and increases complexity

Step-by-Step Solution

Solution:

Step 1: Identify nested if-else problem
Using many if-else instead of polymorphism is called Switch Statements Anti-pattern.
Step 2: Understand why problematic
This reduces extensibility and makes code complex to maintain, matching Switch Statements Anti-pattern; it reduces extensibility and increases complexity.
Final Answer:
Switch Statements Anti-pattern; it reduces extensibility and increases complexity -> Option D
Quick Check:
Nested if-else vs polymorphism = Switch Statements Anti-pattern [OK]

Quick Trick: Replace nested if-else with polymorphism [OK]

Common Mistakes:

Confusing with God Object
Thinking magic numbers relate here
Mixing with shotgun surgery
