Questions and Answers

What is the first concern in the three-step approach to selecting a data structure?

  • Representation for the data
  • Implementation of representation
  • Resource constraints
  • Operations performed on the data (correct)

    • Which key operations normally drive the data structure selection process due to resource constraints?

  • Data deletion
  • Data insertion
  • Data search
  • All of the above (correct)

    • What are the three key questions that should be asked when choosing a data structure?

  • Are all data items processed in order?
  • Is the data structure needed?
  • Can data items be deleted? (correct)
  • Is the data processed in random order?
