Looking at this question, although there are many similar examples out there. I don't see that questions like this add value here, as they tend to be uninteresting for anybody who doesn't have the same assignment or isn't making the same mistake. These questions often are answerable by some of the engineers here, which helps the OP but then in turn encourages more questions of the same flavor.
Is there a consensus about the acceptability (or lack thereof) of such questions here?
