Is your approach malfunctioning? If not, this might be more appropriate for Code Review than for Stack Overflow. If it is, please describe the problem you have. — JaMiT 47 secs ago
Is your approach malfunctioning? If it is, please describe the problem you have. If not, this might be more appropriate for Code Review than for Stack Overflow. Or maybe the question could be improved (for SO) if you explained why you're not sure if the code is good? What looks wrong to you? — JaMiT 1 min ago

@evolutionxbox. I tried doing that also. But there are so many tags that it looks very messed up and the code reviewer wasn't very happy with that style of coding. — Tanzeel 8 secs ago

@charlietfl I’m aware of this. The answers to this question are vast and opinionated. If the OP has a code reviewer they should communicate and think of a solution that works for them. — evolutionxbox 37 secs ago

If anything, you’ll want to ask this at codereview.stackexchange.com. But not in its current form, you’ll have to post a reasonably sized chunk of code as part of the question, not somewhere else. — deceze ♦ 1 min ago
No, questions on Stack Overflow should be about one problem and one specific problem in your code. Again, there is a separate sibling site for code reviews, but read their posting guidelines (too) before a king there. — tripleee 33 secs ago
