Overall the code provided is strong in showcasing the positive and negative cases of SG_UEN. I would only suggest a couplw changes for clarity, but they are not required as the program works fine without them:

1. Separating the test case loop from iterating over the valid and invalid samples, so output isn’t mixed in case later readjustment is needed.
2. Separation of test functions provides clearer output of working cases vs failure.

Neither of these are required, but they just provide better readability, good work.
