3. Consider this flowchart for solving a problem using computational thinking:



What is the correct order of steps in computational thinking?

medium

A. Understand problem -> Break into steps -> Solve each step -> Combine results -> Done

B. Solve each step -> Understand problem -> Combine results -> Break into steps -> Done

C. Combine results -> Break into steps -> Understand problem -> Solve each step -> Done

D. Done -> Understand problem -> Break into steps -> Solve each step -> Combine results
