Most of the people who write the solution in a 8kyu kata are new programmers, many of them don't even know what O notation is, I guess it's the highest ranked because it's easy to understand and easy to think about it. Kata tests do not measure performance, so it is not a flag. I agree with the down buttons. but i think that the kata tests will have any performance input like a lot of inputs or timing. I submit the sort version to, because is the faster way to write the solution, are only to instructions.
yes, and also in some case the word sum will be equals but the words are very diferents. I note it after send the response. how i can modify the test cases of the kata ?
