Decomposition (breaking problems down) in Intro to Computing - Flowchart & Logic Diagram

Process Overview

Decomposition means breaking a big problem into smaller, easier parts. This helps us solve each part step by step, making the whole problem simpler.

This flowchart shows how to start with a big problem, check if it is small enough to solve, if not break it into smaller parts, solve each part, and repeat until all parts are solved.

Step-by-Step Trace - 7 Steps

Step 1: Identify the big problem to solve.

Step 2: Check if the problem is small enough to solve directly.

Step 3: Break the big problem into smaller parts.

Step 4: Work on each small part one by one.

Step 5: Check if all parts are solved.

Step 6: Go back to work on remaining parts.

Step 7: After all parts are solved, finish the problem.
