Finish the solution so that it returns the sum...

Your function always returns 0.

Not a kata issue.

why do i get this "The expression (solution(10)) == ((23)) is false." even though log output is 23 in C programming

Well I just spent 2 hours trying stuff and have no clue where the error is. Found different ways of passing the first 5 tests but never passed the 6th.

I'll return to this kata later on when I'll be more experienced as it's clearly above my level of understanding for now

Your code has an obvious error, I saw it at first glance. Not to presume anything, but just review your code carefully and you will find.

I've created the issue above, thanks for reporting it.

Tests in Go always expect a 2 elements array. Empty or null arrays are not tested.

May I was able to create a kumite and report it for the creator but I will check this issue section too. Thank you for everyone!

Basically, you create a post, describing the problem, mentioning the languages affected and use Issue label.

I am new on this page and I did not found any report possibility. Goggle was useless too. Can you please provide a link how should I report it or add extra test cases? Thank you!
