easy🧠 Conceptual Q2 of 15
LLD - Design — Parking Lot System
Which of the following best describes a race condition in concurrent systems?
AA technique to allocate memory dynamically
BA method to speed up processing by running threads in parallel
CA way to backup data periodically
DA situation where two threads access shared data without proper synchronization causing unpredictable results
Step-by-Step Solution
Solution:
  1. Step 1: Define race condition

    A race condition happens when multiple threads access shared data without synchronization, leading to unpredictable or incorrect results.
  2. Step 2: Match definition to options

    A situation where two threads access shared data without proper synchronization causing unpredictable results correctly describes this unsafe concurrent access causing errors.
  3. Final Answer:

    A situation where two threads access shared data without proper synchronization causing unpredictable results -> Option D
  4. Quick Check:

    Race condition = Unsafe concurrent access [OK]
Quick Trick: Race condition means unsynchronized access causing errors [OK]
Common Mistakes:
MISTAKES
  • Confusing race condition with parallel processing benefits
  • Thinking race condition is a memory allocation technique
  • Assuming race condition relates to data backup
