Which data structure is most suitable for storing the current state and its possible transitions in a game?
AStack
BGraph
CQueue
DArray
Step-by-Step Solution
Solution:
  1. Step 1: Identify the need for state and transitions

    Game states often have transitions to other states, forming a network of connections.
  2. Step 2: Choose data structure that models connections

    A graph naturally represents states as nodes and transitions as edges, allowing flexible navigation.
  3. Final Answer:

    Graph -> Option B
  4. Quick Check:

    State transitions = Graph [OK]
Quick Trick: Use graph to model states and transitions clearly [OK]
Common Mistakes:
  • Using stack which is LIFO, not suitable for arbitrary transitions
  • Using queue which is FIFO, not suitable for state transitions
  • Using array which lacks direct transition mapping
