Excellent, thanks for the sanity check! Issue added.

You are correct! Good catch. The tests should be expanded to invalidate this incorrect solution. Perhaps make an issue in the discussion of the task?

In my testing, this code erroneously returns a false-positive when parsing the string at index one of the list below:

test2 = ["O--#--O", "----O____Odust", "more dust"]

Please let me know if I'm missing something! 🙏

It's quite... something
