LLD - Design — Parking Lot SystemIn a system design diagram, the exit flow is incorrectly shown as the entry point. What is the likely impact of this error?AUsers or data may enter the system incorrectly, causing failuresBThe system will run faster due to reversed flowCThere will be no impact as entry and exit are interchangeableDThe system will automatically correct the flowCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand the role of entry and exit pointsEntry points are where users or data enter; exit points are where they leave. Mixing them causes confusion.Step 2: Analyze the impact of reversing themIf exit is shown as entry, the system may receive data incorrectly, leading to failures or errors.Final Answer:Users or data may enter the system incorrectly, causing failures -> Option AQuick Check:Wrong flow = system errors [OK]Quick Trick: Entry and exit points are NOT interchangeable [OK]Common Mistakes:MISTAKESAssuming reversed flow improves performanceThinking system auto-corrects flowIgnoring the importance of correct flow direction
