The thread you linked is violating our rules:

(9) Edit your posts if you see spelling or grammar errors (don't write in cyberchat or cyberpunk style). English only.

My suggestion is to ignore questions posed by people who are ignoring our rules. This is especially true of folks who are not making a good faith attempt to communicate in English. When you answer a "question" which is expressed so poorly as we see in the linked thread, you should not be surprised to encounter a followup question like you got. Nor should you expect the questioner to take the time to try your code. Or to do anything else that requires a little bit of effort. It is very frustrating trying to help someone like that.

We get a lot of questions posed by people who spell "you" and "are" with a single letter. It would take a lot of effort to chase after each one, point out the rules, and request that they follow them. But doing nothing at all is a very easy punishment to mete out. So just ignore them. And if you try to help them anyway and then get a clueless followup question, just move on to the next thread. It is never to late too ignore a clueless thread.

And if you should happen to see a more serious rule violation, use the report feature to report the thread to a moderator.

From my perspective, the worst threads are the spam. A lot of people sign on to the site only to sell viagra, cell phones, knock-off purses, etc. We give them instant permanent bans and quarantine their threads.
