all-your-base exercise assigns negative numbers to unsigned data types. about c HOT 1 CLOSED

Looking at the example for this I can see that it's only the test helper test_rebase() that uses unsigned parameter types. The implementation itself uses signed types.

My thought would be to keep the implementation using signed types and just correct the test helper to signed types also. This has two benefits. Firstly it allows tests for negative numbers (even if the correct behaviour for negative numbers is to not do a rebase). Secondly, signed types are generally considered safer than unsigned types when checking parameters potentially provided by client code (eg the tests).
