C sample test code has compilation warnings.

Example code that will SIGSEGV the tests, yet has a perfectly reasonable return value:

char **match (const char *p, const char **f) { char **m=calloc (sizeof (char*),1); return m; }

c_ary_eq implementation is deeply flawed: actual being shorter than expected will cause SIGSEGV.

Since you are insisting on modifying the input buffer and return it (which is not tested in any sample or fixed test) you should at least mention this in the description or the initial solution setup. I don't want to guess this from the fact that the signature doesn't declare source as const char*.

This kata is a subject to deduplication process here: https://github.com/codewars/content-issues/issues/147.
Please join the discussion to share your opinions, and help us identify duplicate kata and retire them.

LUA does have a wrong function name in the solution template: s.solution should probably be s.startsWith (except this is part of the kata... which I doubt)

Go translation

D translation

• Description should be language-agnostic

• The five sentence can be classified in a note section and re-worded

The rule asking to remove spaces if input string is NULL doesn't make much sense, and more problematically, it is not tested in random tests.

Doing the NASM-version

I pass the Test, and fail all on Attempt.

Output is :

*Actual*]: "Codewars is an educational community for computer programming. On the platform, software developers train on programming challenges known as kata.[1][2] These discrete programming exercises train a variety of skills in a variety of programming languages, and are completed within an online IDE.[3][4][5]"

[Expected]: "Codewars is an educational community for computer programming. On the platform, software developers train on programming challenges known as kata. These discrete programming exercises train a variety of skills in a variety of programming languages, and are completed within an online IDE."

  [String]: "Codewars is an educational community for computer programming. On the platform, software developers train on programming challenges known as kata.[1][2] These discrete programming exercises train a variety of skills in a variety of programming languages, and are completed within an online IDE.[3][4][5]"

However, it is not what I return.

I output this to the concole just before exiting.

There may very well be errors in the string I return. I do however not return the string listed as actual.

The tests shouldn't log anything.

It looks like the issue which is reported by B4B (it is marked as resolved) is still exist/reborn at least for Python. e.g. solution1, solution2 (the same solution just tried myself to make sure that the issue is reproducible) passed the Tests Suite. The solution will give incorrect results e.g. for case starts_with('axxxxabcxx', 'abc')
