A company wants to develop a software tool that identifies duplicate entries in a large

A company wants to develop a software tool that identifies duplicate entries in a large database while ensuring scalability and accuracy. Which computational thinking steps should be prioritised, and in what order, to achieve an efficient solution?
  1. ADecomposition->Algorithm Design->Pattern Recognition->Abstraction
  2. BPattern Recognition → Algorithm Design->Abstraction → Decomposition
  3. CAlgorithm Design->Abstraction → Decomposition->Pattern Recognition
  4. DAbstraction → Decomposition → Pattern Recognition → Algorithm Design
Show answerHide answer

Correct answer: (D) Abstraction → Decomposition → Pattern Recognition → Algorithm Design

Explanation

For this task the key's order is abstraction first: keep only the important features of an entry. Then decompose the task, recognise duplicate patterns, and finally design the algorithm.
