Q&A

1: Can I use other script languages, like awk or sed, to write this project?

A: Sorry!! The answer is “no”.

2: Is the input decimal or other types?

A: Only decimal.

3: Can I add other options?

A: Yes. If you add others in the project code, please describe them in readme. But the extra score is not too much.

4: What operation should I do, if there is an empty character in the front of a line?

A: There are two ways to do. One is to ignore the space character and get the number.

The other is to ignore the line.
