Choose your learning style9 modes available
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.

Flowchart
Identify the big problem
Break problem into smaller parts
Work on each small part
Go back to work on parts
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.
