As shown in the screenshots below, I passed the unit tests for exercise 2, and there was an error with the unit tests for exercise 4 because of some missing file about which I can’t do anything. When I submitted the assignment, I failed not only exercise 4 but also 2. So, I am not sure what I can do to pass this assignment.
I uploading another screenshot for exercise 2 that shows that I passed the unit tests. The original screenshot didn’t do that. I apologize for any confusion.
Thanks for the suggestion to check the grader output. It showed that I had a couple of issues with how variables were initialized. I was able to fix those and finish the course. Thanks again.
