I hope the people who don't think of using a bitwise operator still get through. I've been programming for ~9 years and have never thought to use it.
Yeah it's secondary so I don't hold it against the ones that didn't come up with it (one person came up with an idea I hadn't considered, I like that a person can think of different ways at all, which was casting the int to string and then checking the last character), it's a minor piece of information. All else being equal I'd like to see knowledge of bitwise operations demonstrated (and I'm sad to say that at my wo…
That's a fairly reasonable approach. Looking for creativity in a relatively mundane problem is probably a good thing. The bitwise operator thing, if it actually needed to be used like you say, could be more appropriate for a coding standards guide if the candidate was otherwise suited. The immediate comparison I made, though admittedly contrived, was to that of the comma operator which I just learned about. Unlike self executing anonymous functions—which I'd consider hard to understand but critical to know—, they both fall into the category of fairly obscure pieces of syntax.
