Idk why but the example "59544965313" crashes my program on code wars but when I test it in my main it works perfectly fine, someone?

Thank you, my bad i should have seen the tests down there.

Oh, I'm using C.
It's what I said, when i try to test or attempt the tests are always a "Log". Then even if the answear is 1 or 0 it's always wrong.

So when I try to attempt or test it appear that log is a valid option i guess, idk waht this means.

thank you , im stupid, i have been confused all day for this xD

So, this is saying that my code is wrong because -5 ins't a prie number, but it is or am I dumb?
