I agree with this issue - getting the same error when attempt my solution.
The issue for me seems to be that I'm writing in python. And the tests will generate something like: -79--73 in the list.
Which python will interpret as -79 minus -73
So the list won't include "-79--73", but instead will have -6 in its place.
