To be fair though, reversing a string is not the kind of thing a lot of people deal with - there's usually a library function. Now they should be able to puzzle it out, but if it takes them a moment I'd be generous because I at least put it into the box of "that sounds easy, but oh wait a minute it's slightly different from my usual dev pattern".
To put it another way - when I code it's rarely different from writing to me; code is simply an expression of thought. But when you ask me to do something that seems a bit artificial (reverse a string) it's like asking me to write a haiku - I can do it, but give me a moment while I count out my syllables.
