This?
I should add, the problem you had on SO is that they generally prefer you come and present the work you’ve already done to solve the problem you’re having. So no, they don’t do the code for you. But they will look over code you have and suggest fixes. You have to put the work in. What you could have done was discussed what you looked up and some of the research you did and how it pertains to your question. That would have filled up your character requirement with relevant/useful information.
