Computational Thinking & Problem Solving

Computational Thinking

  • A "computer person" = skilled in computational/algorithmic thinking.
  • Computational thinking: methodical, step-by-step reasoning \Rightarrow define terms clearly so others can follow.
  • Core cycle: Input \rightarrow Algorithm (stepwise) \rightarrow Output.

Computer Science vs. Programming

  • Computer science = discipline of problem solving.
  • Programming = tool to implement solutions, not the essence of CS.

Applicability

  • Concepts apply across domains: software, hardware, AI, ML, data science, etc.
  • CS provides a mental model + practical skills transferable to other fields.

Problem-Solving Model

  • Any problem: identify inputs, design algorithm (black box for now), obtain outputs.
  • Focus on how to transform inputs to desired outputs via precise steps (to be detailed later).
