part of #1824

This is simply a manual expansion of the macros. There is no canonical data from problem specifications, so the tests won't change often and the maintenance burden of the duplication should be acceptable.

This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.
