We have re-run the HW4req tests and similarity checks and updated the PDF.
LET ME KNOW if you have submitted your HW in the wrong course, and I will place you in the proper list.
Here is a second draft of the HW4 required grades.
For any doubt, comment below.
You can already check the errors on secret tests (if any) in your personal results page (tab Correctness).
This is the zip with our solutions and with secret tests.
EDIT: as usual, in case your code is marked as "too similar" to someone else's you must do and submit the HW4 recover (that will be published shortly).
