review of Lab1a

The repo is structured in a way that seems to work, but I think it was a bit unclear when there was multiple Lab1a files.

Outtext is correctly updated, as the string is reversed And the code is well commented, however, you miss a bit commenting on "check" and "write" which would be great for following the code.

Overall, the code is well done and shows good structure and commenting but could be refined for clarity and correctness.
