[C] My solution gives all the expected tests but although I get an error in this test:
"The expression (as strings) (strsum("00001", "9")) == ("10") is false: actual=580 expected=10".
And this is not true!!!. My code gives "10":
And my solution was indeed accepted and I got the score.
So what will you do if this happens to you too?
So. After you have clicked on test, you will see the error but just ignore it.
Click on attempt and you will see that your solution has been accepted. (of course, if you don't have random errors).

To my opinion if you would solve the kata in C language you would see that in C it's not simple because of the exact dynamically allocation that you need

Sorry I got my mistake (only after I tried to attempt I got the right error).

And as for what they wrote to me to do a separate test on each test,
so I did one by one and for me everything comes out completely normal?

Thankes.but I didn't understand what you said "but did you try calling your function several times in a row?"
can you please re-explain it to me?

I solve the kata in C and got this Error.
(Explanation => Expected resault same as Actual resault. Except that my resault has a space at the beginning).
But this isn't true, I don't have a space.
is anybody encountered in this problem.
