I have same problem, even i write something like this and it does not work, if return true or false

    if(s=="" & part1=="code" & part2=="wars"){
        result = false;
    }

Your solution probably isn't efficient enough. Some of the inputs can be quite large, like 20,000 characters or more.

Hi, my code passes all testes but when i click Atempt to finish whole Kata, an Time Out error apears

Your code only checks if there is a "z" in the sentence.

Also, please mark your comment as spoiler if it contains code.
