Fixed.

Thanks for reviewing this two years later! I copied abab and acac to the sample tests for a little more information and fixed your other two suggestions.

• tests should use cr_expect_* instead of cr_assert_* so that the tests keep going even if an assertion fails. This is a puzzle and people are going to hit Submit until they see the pattern.
• adding a few more sample tests would be nice, seeing how many people are complaining in the comments
• if (x) free(x); is useless, since free(NULL) is valid.

very long lines disable syntax highlighting, so primes[] = should be formatted differently in the test cases

C translation

hello, how does it work?
what kind of wicthcraft is this?

how it works?

Assembly disguised as C. It is brilliant!

No, asking for a wrong result with a relative error up to 1e-3 when simple floating point calculations have realtive errors of 1e-15 – 1e-17 doesn't make sense and doesn't respect codewars guidelines.

Could I still ask for a 3 decimal places answer? Using approximate equality of course.
