should have been raised as an issue. no UB here, just a mistake on my part, an == that should have been a != during comparison when either of the words was a null pointer. fixed.

I'm Happy to finish this challenge (if I calc the time that I spend to solve It take like 1day or 2day)

??

I don't know about your solution, but with C this is not uncommon to happen. This sometimes happens due to undefined behavior (UB) coming from your solution and influencing the tests. I was told that it's difficult / impossible to combat this from tests' side.

I only wrote code for returning words count, the array function words_to_array is empty.Solution got aproved. It does not check the array?

but you should specify what the problem actually is, because I'm not seeing it ( granted, I don't know much C ).

should mark this as an issue

You need to return this result, not print it to console.

Using python 3.11, getting the following results.

Forked and approved

Yeah you Right about all that.
Thank you for all, I will still work on solution to find it.
Again Thank you
