Is using sample I/O violate the code of ethics

[Magicbook1108]

It appears that the test list is not being used, and only the sample I/O is utilized in the code verification process. Based on this, I have two questions:

1. Is it appropriate to use sample I/O for code verification to improve code correctness? Does this practice violate ethical standards?
2. What impact would incorporating the test list into the evaluation process have? Would it enhance the evaluation's comprehensiveness or change the results?
