Not sure what's going on, but you have to pass the tests on CW that your foreign environment does not handle. If you want help, post your code with proper markdown and a spoiler tag. I'll take a look for you.

I've just passed my code to another compiler and it's working, but here it isnt. Can someone help plz?(i made de code on c and the another compiler is on gcc 9.1.0)

No, the problem is with your code, how do you explain 13k solutions if not? Do what I told you so I can see what you did wrong, otherwise it's you saying your code is right and me saying it's not.

if its saying true in codewars the problem is with the kata, bc there is no 'n' in the sentence.

A problem with your code isn't a kata issue, post your code using markdown formatting and mark your post as having spoiler content. There are almost 13k completions in Python already.

Can u plz explain to me what do u mean by case(I do not speak english fluently)?
