What is the main purpose of iteration in problem-solving?

• A. To create a more efficient solution by repeating steps
• B. To store data permanently
• C. To convert colour spaces
• D. To reduce file size by compression

Answer: (A)

Iteration means repeating a process and using what you learn from each run to improve the result. In problem-solving, you try a solution, see how well it works, adjust what you did, and try again. Each cycle helps you spot and fix issues, optimize the steps, and move toward a more efficient or effective solution than the first attempt. So the main purpose is to refine and improve by repeating steps. The other options describe one-off tasks—storing data, converting colour spaces, or compressing files—that don’t inherently involve repeatedly refining the solution.
