Your hero for the day!
We had what I thought was a completely grueling homework question in M202. One person finished it very quickly and labeled the rest of us “a braindead” for not being able to do so (great encouragement right…and yes that was the grammar he used). The majority of the students seemed to have a problem with it, as I did. To be fair to the assignment, they did throw us a link to the following StackOverflow link. This is probably where those of us who are braindead failed the test.
