Another exercise I’m trying to sync up with problem specifications on the Rust track.
Rust has tests for negative numbers, e.g. rotate("m", -1) == "l".
The problem specification only has positive numbers in the tests.
I could upstream these tests or keep them around as additional, track-specific tests.
But I’m leaning toward removing them. The code students need to write to support negative numbers is easy and uninteresting. Also, I can adjust the signature of the rotate function to only accept unsigned integers.
The instructions state: “integer key between 0 and 26.”, so I see no reason to have these additional tests.
What do you think?
