Describe the characteristics of a good algorithm.

Here are the characteristics of a good algorithm in 10 short points:

1. Correctness: Produces the correct output for all valid inputs.

2. Efficiency: Optimizes resource use, including time and space.

3. Clarity: Easy to understand and follow, with clear steps.

4. Simplicity: Avoids unnecessary complexity; straightforward solution.

5. Finiteness: Terminates after a finite number of steps.

6. Generality: Applicable to a range of inputs and scenarios.

7. Optimality: Provides the best possible solution for the problem.

8. Modularity: Designed in independent, reusable components or functions.

9. Adaptability: Flexible to changes in input size or problem constraints.

10. Scalability: Handles increasing input sizes effectively.
