This flowchart shows the step-by-step process to make a cup of tea. Each step is clear and follows the previous one in order:

• Start: Begin the process.
• Boil water: Heat water until it boils.
• Add tea leaves: Put tea leaves into the cup or pot.
• Steep tea: Let the tea leaves sit in hot water for some time.
• Pour tea: Pour the brewed tea into a cup.
• End: The process is complete.

This shows why algorithms are step-by-step solutions: they give clear instructions to follow in order to get the desired result.
